Survive the Purple Crater Selenians Mining Base
This guide gives a single, uninterrupted, deeply practical walkthrough for finding, entering, clearing, and extracting from Selenian’s Mining Base in StarRupture. It covers everything from exact approach landmarks and loadout numbers to room‑by‑room tactics, spawn behavior, blueprint handling, extraction routes, and advanced solo and co‑op strategies. Read straight through for a complete run plan you can execute on your next session.
Location and landmark orientation
Selenian’s Mining Base sits northwest of the crash site and is commonly referred to by players as the purple haze outpost because of the large purple bloom and the cratered ground nearby. The easiest way to find it is to leave the lander and head toward the jagged mountain with a broken satellite dish embedded in its slope. That satellite wreck is the primary visual cue; the base itself is a compact complex of rusted metal buildings clustered at the mountain’s foot. The largest structure is a two‑storey building with a locked front entrance and an accessible rear face that has a climbable rock ledge. The blue storage chest you need is inside that largest building, typically on a lower floor beneath the rooftop entry point. Expect the area to be a hotspot for spawns and patrols; the environment funnels you into predictable choke zones, which you can exploit or avoid depending on your playstyle.
Why this base matters
The primary reason players assault Selenian’s Mining Base is to secure the Tube Blueprint and often the Rotor Blueprint, both of which unlock mid‑tier fabrication components that accelerate base automation and vehicle upgrades. These blueprints are found in the blue storage chest inside the main building. Picking up the blueprints frequently triggers an additional spawn wave, so the run is a short, high‑intensity raid: fast in, precise in combat, and fast out. The payoff is significant for progression, but the risk is real if you linger or come underprepared.
Preparation and exact loadout
Preparation is the single biggest determinant of success. You need to balance ammo, healing, mobility, and crowd control. Below are the exact items and counts I recommend; these are tuned for a solo player who wants a high chance of success without relying on teammates.
Primary weapon: Long‑range rifle or designated marksman weapon with at least 200 rounds. Use a scope to pick off patrols before you commit.
Secondary weapon: Reliable automatic or burst rifle with 100 rounds for close to mid range.
Sidearm: Fast‑draw pistol with 30–50 rounds for emergency finishers.
Healing: Carry 3–5 medkits depending on your confidence; use one at 60% health and another at 30% as a rule.
Armor repair: At least 1 full repair kit; repair between fights.
Crowd control: 2 grenades or one grenade and one stun device; these thin swarms in corridors.
Mobility tool: Grapple, jump booster, or stamina booster if available; it shortens the climb and gives escape options.
Consumables: One damage amp or armor buff if you have it; it helps with elites.
If you prefer co‑op, reduce medkits to 2 each and split roles: one player focuses on long‑range suppression while the other handles close quarters and chest retrieval.
Pre‑run checklist
Confirm these three things before you leave the lander: you have ~300 rounds total, at least 3 medkits, and a mobility option. If any of those are missing, delay the run until you can resupply. The base’s spawn density punishes low ammo and poor mobility.
Approach and reconnaissance
From the lander, head northwest toward the satellite wreck. Keep to high ground where possible to scout patrol routes. The outpost’s perimeter is ringed by low walls and organic growths that spawn small swarms; these spawn points are visible as faint purple spores on the ground. Use binoculars or your scope to mark two things: the patrol path of the larger acid‑spitting variants and the location of any elite sentries. If you see a patrol crossing the front of the main building, wait for it to pass or take it out from a distance. Do not approach the front door; it’s locked and often bait for ambushes.
Circle to the right side of the complex and look for the climbable rock face behind the tallest structure. This is the intended entry route: it lets you bypass the locked front and drop into the top floor where you can clear rooms downward. If you have a mobility tool, use it to shorten the climb and reduce exposure time. If you don’t, take the natural ledges and time your jumps to avoid spore clouds that slow movement.
Entry sequence and room clearing
Once you reach the rooftop entry point, pause and scan. The top floor is usually less populated but can contain a patrol or two. Clear the rooftop first with long‑range shots and a grenade if necessary. Move slowly and listen for audio cues—many of the base’s enemies have distinct movement sounds that give away their approach. Enter the top room and secure it before moving to the stairwell. The stairwell is the most dangerous choke because it funnels enemies into a narrow corridor; use a grenade at the stairwell landing to thin groups before descending.
Work methodically: clear the top floor, then the mid floor, then the ground floor where the blue storage chest is usually located. When you approach the chest, check for tripwires or hidden spawners in adjacent rooms; some runs have a hidden nest that triggers when you open the chest. If you suspect a spawn, set up a defensive position with a clear line of sight to the chest and a fallback route to the stairwell or rooftop.
How to open the blue chest safely
Approach the chest with your back to a wall so you can’t be flanked. Keep your long‑range weapon ready to pick off any elites that appear, and have a grenade primed for immediate use. Open the chest quickly, grab the Tube Blueprint and any additional loot, then immediately move to your preplanned extraction route. Do not loot other containers or linger to search for rare items; the chest is the objective and the spawn trigger is real.
Handling the spawn wave
Expect an immediate spawn wave after chest pickup. The composition varies: small swarms, acid spitters, and occasionally an elite guard. Your response should be disciplined: fall back to a chokepoint you cleared earlier, use grenades to break up swarms, and focus heavy ammo on acid spitters and elites. If you have a teammate, one player should hold the chokepoint while the other covers flanks. If solo, use the rooftop as a fallback sniper perch; it gives you vertical advantage and time to heal and repair armor.
Combat tactics and aim priorities
Aim for weak points. For most enemies, headshots or center mass with high‑velocity rounds are best. Acid spitters are priority targets because their ranged attacks can force you out of cover and into vulnerable positions. Use suppression fire to keep swarms pinned while you reposition. When fighting in corridors, step back to widen the engagement area and avoid being cornered. If you’re low on ammo, switch to your sidearm and use melee finishers only when safe.
Movement and positioning
Movement is as important as aim. Keep moving between cover points and avoid standing in open areas where multiple spawn points can converge. Use the environment: crates, stairwells, and broken walls provide temporary cover and sightlines. If you’re carrying the Tube Blueprint, avoid risky jumps or long exposure; treat the exit like a sprint with intermittent suppression fire.
Extraction routes and timing
Your extraction route should be planned before you open the chest. The fastest route is usually the same path you used to enter: climb down to the ground floor, exit through the rear alley, and sprint along the ridge back to the lander. If the rear path is blocked, use the rooftop to traverse to an adjacent building and drop down on the far side. Time your sprint between spawn waves; if you see a lull after the chest pickup, move immediately. If the spawn wave is heavy, hold a defensible position until it clears, then sprint.
What to do if you die after pickup
If you die after picking up the blueprints, prioritize recovering your gear if you can respawn quickly. If recovery is unlikely, plan a second run with a partner and adjust loadouts to be more conservative: more medkits, more crowd control, and a dedicated reviver role in co‑op.
Blueprint handling and fabrication
Once you have the Tube Blueprint and any additional blueprints like the Rotor Blueprint, return to your base and register them at the Recipe Station or Fabricator. Tubes and Rotors are components used in mid‑tier production lines and vehicle upgrades; unlocking them early accelerates your automation and mobility options. If you plan to mass produce, set up a dedicated fabrication line and stockpile raw materials before attempting multiple runs.
Solo versus co‑op strategies
Solo runs require discipline: conservative ammo use, methodical clearing, and a strict extraction plan. Co‑op runs allow role specialization. A recommended two‑player setup is: Player A (sniper/suppressor) carries the long‑range rifle and focuses on picking off patrols; Player B (breacher/looter) carries the automatic weapon, crowd control, and the mobility tool to reach the chest quickly. Communication is key: call out patrols, mark chokepoints, and coordinate grenade use. In three‑player squads, add a medic role to keep everyone topped up and a reviver to reduce downtime.
Advanced tactics and tricks
Use verticality to your advantage. Many players approach from ground level and get overwhelmed; the rooftop entry reduces exposure to ground spawns and gives you sightlines to pick off elites. If you have a drone or deployable turret, place it on the rooftop to cover your rear while you loot. Use baiting: throw a noise maker or grenade to draw patrols away from the chest, then sprint in and out. If you’re speedrunning, practice the climb and drop sequence until you can do it without stopping; shaving seconds reduces the chance of additional spawns.
Resource conservation and economy
If you plan repeated runs, conserve resources by using melee finishers on small swarms when safe and saving heavy ammo for elites. Recycle excess loot at your base to fund medkits and repair kits. Prioritize crafting mobility upgrades that reduce climb time; they pay off over multiple runs.
Troubleshooting common problems
If you repeatedly die to acid spitters, change your approach: pick them off from distance before entering the complex. If you get overwhelmed in stairwells, clear the stairwell with a grenade before descending. If the chest spawn is inconsistent, try slightly different entry angles; spawn logic can vary and a different approach sometimes prevents the hidden nest from triggering.
Psychological pacing and risk management
Treat the run as a short, high‑risk investment. Don’t let greed make you linger. The chest is the objective; extra loot is optional. If you’re low on medkits or ammo, abort and resupply. A single successful blueprint run is more valuable than multiple failed attempts that cost resources and time.
Post‑run actions and follow up
After a successful extraction, immediately register the blueprints and craft a small batch of Tubes or Rotors to confirm the recipe. Use one or two crafted items to test production and ensure you have the required raw materials. Then plan your next run: restock ammo, repair armor, and consider bringing a teammate to speed up future runs.
Playstyle variations
If you prefer stealth, use suppressed weapons and avoid killing patrols unless necessary; this reduces spawn density but requires precise timing. If you prefer aggressive play, bring extra grenades and heavy ammo and clear the area quickly, then loot and sprint. Both styles work; choose the one that matches your comfort with risk and resource consumption.
Common mistakes to avoid
Do not approach the front door; it’s a trap. Do not open the chest without a preplanned extraction route. Do not use all your medkits before the chest pickup; save at least one for the exit. Do not ignore armor repair; a single repair can be the difference between surviving the exit and losing everything.
Speedrun notes
For speedrunners, the ideal run is a clean climb to the rooftop, a single grenade to clear the top floor, a quick descent, chest open, and sprint back. Practice the climb and the drop to shave time. Use a mobility booster and a light loadout to maximize sprint speed. Speedruns are high risk but can be repeated quickly if you accept occasional failures.
Co‑op role checklist (minimal)
Player A: Long‑range suppression, marks patrols.
Player B: Breach and chest retrieval, crowd control.
Player C (optional): Medic and reviver.
Environmental hazards and how to read them
Purple spores on the ground indicate spawn points. Acid pools slow movement and damage over time; avoid them. Broken satellite debris can block sightlines—use it as cover or avoid it if it funnels enemies. Listen for audio cues; many enemies have distinct sounds that let you pre‑aim.
How to adapt when things go wrong
If a spawn wave overwhelms you, retreat to a defensible rooftop or chokepoint and heal. If you lose a teammate, decide quickly whether to recover or extract; sometimes abandoning a downed player and extracting with the blueprints is the pragmatic choice. If you lose the chest to a despawn or glitch, reset the area by leaving and returning in a new session.
Long term progression value
Securing the Tube Blueprint and Rotor Blueprint accelerates your mid‑game by enabling automated production and vehicle upgrades. These components unlock new build options and reduce grind. Prioritize blueprint runs early in your progression to compound benefits over time.
Final run plan summary
Approach northwest from the lander, scout from high ground, circle to the right, climb the rear rock face, clear the rooftop, descend methodically, open the blue storage chest, expect a spawn wave, fall back to a chokepoint or rooftop, and sprint to extraction. Keep ~300 rounds, 3–5 medkits, armor repair, and crowd control. If co‑op, split roles into suppression and breaching.
FAQ
How close is Selenian’s Mining Base to the lander and how long does a typical run take? The base is a short trek northwest from the lander; a practiced solo run takes 4–7 minutes, co‑op runs can be faster. Can I solo the base early game? Yes, with careful ranged play, the recommended ammo counts, and conservative healing. Expect to retry a few times while learning spawn patterns. Do blue chests respawn in the same session? Blueprints are one‑time pickups per run; to get them again you must revisit in a new session or wait for the game’s respawn mechanics to refresh the area. What triggers the extra spawn wave? Opening the blue chest commonly triggers additional spawns; sometimes the spawn is tied to nearby nests or hidden triggers. Always assume a spawn will occur. What’s the best weapon combo for this run? A long‑range rifle for patrols and a reliable automatic for close fights is the most versatile combo. Add a fast sidearm for emergencies. Should I loot other containers? Not on your first run. Prioritize the chest and extraction. If you have time and resources, you can sweep for extra loot on subsequent runs. What if I keep getting overwhelmed in stairwells? Use grenades to clear stairwells before descending and hold the top of the stairs to pick off enemies as they funnel up. Is co‑op worth it? Yes. Co‑op reduces risk, allows role specialization, and increases success rate, especially for players still learning the spawn patterns. How do I register blueprints after extraction? Return to your base’s Recipe Station or Fabricator and register the blueprint to unlock crafting recipes for Tubes and Rotors. Any last minute tips? Don’t be greedy; the chest is the objective. Practice the climb and extraction route until it becomes muscle memory.

Concise Waypoint Map with Step Timestamps for a Speedrun
Assumptions: You start at the lander, solo or two‑player, minimal detours, practiced climb. Times are target goals for a practiced run; adjust for latency and loadout.
0:00 Leave lander Move northwest immediately. Keep sprint bursts between cover. Use a scope to scan the horizon for the satellite wreck.
0:20 Satellite wreck sighted You should see the jagged mountain and purple crater. Slow to a jog and mark patrols visually. If a patrol crosses the front, wait 3–5 seconds or take a single long‑range shot to thin it.
0:35 Reach outpost perimeter Circle right along the low wall. Avoid the front door. Use the right flank to approach the climbable rock face behind the tallest building.
0:50 Start climb Use mobility booster or timed jumps. If you have a grapple, hook to the top ledge and pull. Keep movement steady; avoid spore patches that slow you.
1:05 Rooftop entry Drop into the top room. Pause 1–2 seconds to scan. Clear any rooftop patrols with two precision shots or a single grenade if clustered.
1:20 Secure top floor Move to stairwell entrance. Throw a grenade into the stairwell landing to pre‑clear potential funnel spawns.
1:30 Descend to mid floor Clear methodically. Use suppression fire to keep small swarms pinned. Repair armor if below 70%.
1:45 Ground floor approach Move to the room with the blue storage chest. Back to the wall, chest in sight, long‑range weapon ready, grenade primed.
1:55 Open chest and grab blueprints Open quickly, grab Tube Blueprint (and Rotor Blueprint if present). Immediately move to extraction route; do not loot other containers.
2:00–2:20 Spawn wave handling Expect immediate spawns. Fall back to stairwell chokepoint or rooftop sniper perch. Use grenades to break swarms and heavy ammo on elites.
2:30 Sprint to extraction When the spawn thins, sprint along the ridge back to the lander. Use mobility booster for exposed gaps.
3:00 Land at lander If all goes well, you’re back at the lander and can return to base to register blueprints. A practiced run aims for 3 minutes; allow up to 5 minutes for conservative play.
Speedrun notes
Practice the climb and drop until muscle memory removes hesitation.
If a patrol blocks the right flank, a single long‑range takedown saves time.
If you die, reset and focus on shaving one risky action per run rather than rushing everything.
Co‑op Role Script for Two Players and Three Players
Overview: Assign clear roles before you approach. Communication is the force multiplier. Use short, consistent callouts and a single extraction plan. Roles below are optimized for success with minimal bullets and limited medkits.
Two‑player script
Player One — Suppressor (Long Range) Loadout focus: long‑range rifle, 200 rounds, one grenade, 1 medkit. Primary tasks: scout from high ground, pick off patrols, call out elite positions, hold rooftop or high vantage during extraction. Callouts: “Patrol left,” “Elite down,” “Rooftop clear,” “Spawn incoming.” Engagement rules: engage patrols at 150–200 meters; do not push into stairwells. If Player Two is breaching, provide suppression on demand.
Player Two — Breacher (Close Quarters) Loadout focus: automatic rifle, 100 rounds, 2 grenades, 2–3 medkits, mobility tool. Primary tasks: circle to the right, perform the climb, clear rooftop and stairwell, open the blue storage chest, and sprint to extraction. Callouts: “Climb start,” “Top clear,” “Chest open,” “Need cover.” Engagement rules: move fast, prioritize chest, avoid prolonged fights. If suppressed, call “Hold” and retreat to rooftop.
Two‑player sequence
Both leave lander; Suppressor takes high ground and marks patrols.
Breacher circles right and starts climb.
Suppressor eliminates or pins patrols.
Breacher secures rooftop, clears stairwell, opens chest.
Suppressor covers extraction and focuses heavy ammo on elites.
Both sprint to lander; Breacher carries blueprints if inventory rules require.
Three‑player script
Player One — Marksman Loadout: long‑range rifle, 200 rounds, 1 medkit. Role: overwatch, pick off distant patrols, call out spawns.
Player Two — Breacher Loadout: automatic, 100 rounds, 2 grenades, mobility tool, 2 medkits. Role: climb, clear rooftop and stairwell, open chest.
Player Three — Medic/Support Loadout: light rifle or SMG, 80 rounds, 3–4 medkits, armor repair, stun device. Role: stay mid‑range to revive, repair armor, and throw stuns into stairwells or chokepoints.
Three‑player sequence
Marksman secures high ground and calls patrol timing.
Breacher climbs and secures rooftop.
Medic positions at mid building to cover stairwell and revive if needed.
Breacher opens chest; Medic immediately moves to the stairwell to block flanks.
Marksman focuses heavy targets; Medic revives or heals as needed.
Team extracts together; Medic carries extra medkits for the sprint.
Standard callouts and shorthand Use short, consistent phrases: “Climb,” “Top clear,” “Stairs hot,” “Chest open,” “Spawn left/right,” “Elite down,” “Extract now.” Keep voice comms minimal and decisive.
Contingency rules If Breacher is downed before chest: Marksman suppresses while Medic attempts revive; if revive fails, extract without chest. If heavy spawn overwhelms stairwell: fall back to rooftop and hold until Medic stabilizes team.
Role tips
Marksman should conserve heavy ammo for elites and acid spitters.
Breacher should carry the mobility tool and be the fastest mover.
Medic should prioritize armor repair between fights and keep one medkit reserved for the exit.
Final quick reminders Objective first: the blue storage chest is the mission goal. Plan extraction before opening the chest. Use vertical advantage whenever possible. Communicate with short, clear callouts.
