Completing Switching The Supply quickly gives you efficient access to its rewards, unlocks quest chains, and helps you grind materials or rep that depend on timely completion. Whether you’re farming for upgrade parts or racing leaderboards, speed and reliability matter. This guide focuses on execution and consistency so you can finish the quest today with minimal retries.
Before you start: Prep checklist
Ensure your mech and pilot are fitted for mobility and survivability.
Stock consumables (healing packs, overcharge modules) and mobility boosters.
If playing co-op, assign one player as navigator and one as valve operator.
Familiarize with jump, dash, and climb mechanics for tunnel shortcuts.
Equip at least one close-quarters weapon and one ranged or crowd-control tool.
Basic mission objective
In Switching The Supply, you’ll navigate the Spaceport tunnels, locate a control valve, and interact with it to reroute or restore supply lines. This triggers enemy waves and environmental changes; survive and secure the exit to complete the quest.
Recommended loadouts
Solo speedrun (priority: mobility + sustain)
Primary: High-rate-of-fire or hitscan SMG (for close tunnel fights)
Secondary: Short-cooldown shotgun or energy pistol for stagger
Utility: Mobility module (dash/boost battery), small shield module, quick heal stim
Passive: Speed or stamina regen perks
Co-op (priority: role synergy)
Navigator/Scout: High mobility, stealth or suppression module, scanner
Heavy/Anchor: Shield generator, area denial (grenade or turret), high DPS
Support: Healer module, pulse debuff, ammo support
How to approach the Spaceport tunnels
The Spaceport tunnels are tight, linear, and often contain choke points and vertical shafts. Use mobility to avoid prolonged firefights. Map familiarity is your biggest time-saver—memorize the few branching nodes and the valve room entrance.
Move fast through open sections; avoid unnecessary engagements.
Clear corners with quick pulses or grenades to avoid being flanked.
Use jump-dashes to bypass low obstacles and reach higher catwalks that give sightlines to the valve room.
Step-by-step walkthrough (fastest route)
Use this as your primary route when you want the quickest completion. Every step is optimized to reduce downtime and limit backtracking.
1. Mission start and immediate sprint
As soon as the mission begins, sprint toward the nearest tunnel entrance. Ignore side rooms and optional caches unless you need ammo or a heal.
Use dash to cover ground and to pass through narrow chokepoints before enemies can fully commit.
2. First choke and scanner ping
You’ll hit your first short choke point with a pair of standard grunts and a turret. Burst them down or bypass with a mobility dash.
Ping the map or use scanner module to mark the valve-bearing corridor in your HUD.
3. Vertical shaft shortcut
After the choke, look for a vertical shaft on the left (usually marked by stacked containers). Jump and climb to the catwalk—this skips a longer corridor and gives a direct line to the valve room.
4. Tunnel curve and ambush
The tunnel curves and narrows; expect an ambush with shielded units. Use grenades or your shotgun to stagger. If you’re low on health, fall back to the catwalk and use ranged fire while moving.
5. Valve room entrance
The valve room usually sits past a short corridor with overhead piping. Clear this corridor methodically; take the high ground to neutralize ranged enemies who camp the door.
6. Interacting with the valve
Approach the central valve. When you begin the interaction, be prepared—this triggers a scripted enemy wave. Position behind cover with sight lines to the entrance and any side flanks.
7. Defend and finish
Use your area-denial or team stagger to hold off waves until the valve fully switches. If solo, kite in a circular motion around the valve cover and pop heals between hits.
8. Extraction
After the wave, the mission markers update to the extraction or the next objective. Follow the marked route; often there’s a short sprint to an elevator or shuttle.
Detailed room-by-room breakdown
Initial corridor
Enemies: Light grunts and patrol drones.
Tactics: Single bursts; conserve grenades.
Catwalk shaft
Enemies: Snipers or ranged sentries appear occasionally.
Tactics: Rush the catwalk, use mobility to close distance; avoid hanging around.
Spiral junction
Enemies: Mixed units with one heavy shield.
Tactics: Focus the heavy shield first or bait it into narrow doorways to contain its movement.
Valve corridor
Enemies: Reinforced waves with stagger, explosives, or turrets.
Tactics: Use cover, anticipate spawn points, have a rotation for healing.
Enemy spawn behavior and counterplay
Grunts: Fast, low HP. Use AoE or rapid-fire to prevent flanking.
Shielded units: Slow with high resistances. Flank or use heavy stagger.
Turrets: Fixed; destroy them first or use EMP/electromagnetic burst.
Reinforcements: Spawn during valve interaction—use choke points to funnel them.
Movement tricks to save time
Dash-canceling: Immediately dash after a melee or animation to preserve momentum.
Catwalk bunny-hop: Use jump-dash in sequence on catwalks to maintain sprint speed and avoid fall damage.
Wall-clip skip: In certain tunnel seams you can slide along thin ledges to skip small platform sequences; practice in low-risk runs.
Solo vs Co-op nuances
Solo
Play conservatively during valve interaction—there’s no teammate to revive you.
Prioritize healing and mobility modules.
Use environmental cover and constantly reposition.
Co-op
Assign explicit tasks: one player starts valve, one watches the flank, one secures the back door.
Use shared tactics like stagger combos and synchronized grenades to minimize wave duration.
Communicate spawns—knowing where reinforcements come from saves lives.
Consumables and mods to carry
Quick stim: Instant health during valve defense.
EMP grenades: Disable turrets and sentries during valve interaction.
Overclock modules: Short boost to weapon fire rate or dash cooldown.
Resupply packets: Use only if the run becomes prolonged.
Common mission pitfalls and how to avoid them
Pitfall: Getting pinned behind the valve while interaction completes.
Fix: Place a mobile shield or use a distraction ability to bait enemies away while you finish the interaction.
Pitfall: Running out of ammo before extraction.
Fix: Bring an ammo support mod or avoid long-range spray on single targets. Conserve by switching to sidearm in close quarters.
Pitfall: Co-op poor role clarity (everyone runs same loadout).
Fix: Assign roles pre-mission and set expectations: navigator, anchor, support.
Pitfall: Ignoring vertical shortcuts.
Fix: Learn the shaft and catwalk cues in low-stakes runs; the time saved compounds with repetition.
Speedrun strategies (minutes saved per optimization)
Immediate sprint and shaft skip: saves 30–60 seconds.
Valve pre-position (waiting near cover): saves 15–30 seconds by lowering reposition time during waves.
Coordinated grenades on wave spawn: saves up to 45 seconds by wiping faster.
Using overclock dash cooldown mods: reduces downtime and traversal time by ~20%.
Loot, rewards, and quest progression
Completing Switching The Supply yields mission rewards that often include upgrade parts, crafting mats, and quest progression tokens. If the mission is part of a larger chain, finishing fast can unlock time-limited events or cumulative objectives tied to daily or weekly missions.
Prioritize mission objectives over optional caches if your goal is speed.
If farming for a specific drop, run the mission repeatedly and vary your RNG by changing difficulty to improve drop tables.
Troubleshooting mission bugs and common errors
If the valve interaction fails to trigger: exit the immediate area (drop into a previous room) and re-enter; the trigger often reinitializes when players re-enter the trigger radius.
If enemies stop spawning mid-wave: leave and re-enter the valve room; waves usually repopulate.
If a teammate disconnects during interaction: pause your own interaction and wait for reconnection where practical, or continue if confident you can solo the wave.
Practice runs and training mode suggestions
Do 3 low-stakes practice runs focusing only on navigation to memorize the shaft skip and valve approach.
Time each segment (start to shaft, shaft to valve, valve to extraction) and aim to shave at least 10% each session.
Use lower-difficulty runs to test weapon combos and grenade placement for waves.
Advanced strategies and playstyles
Aggro-control playstyle: Use stun and suppression mods to control wave tempo while finishing the valve. Best for solo players who prefer methodical clears.
Hit-and-run: Use speed, dash, and short engagements to take out priority targets only then return for valve interaction. Best for players with high mobility builds.
Anchor-and-bait: In co-op, one player anchors at the valve with a powerful shield; other players route and pick off spawns. Very effective for high-difficulty versions.
Visual and audio cues to watch for
Audio: A low mechanical whine usually indicates the valve activation sequence is near.
Visual: Overhead pipes and a large circular wheel indicate the valve room entrance—learn these landmarks.
Spawn cues: Flashing red lights in side alcoves often signal imminent reinforcements.
How to record runs for sharing or review
Use the in-game capture or external software and timestamp the start, valve interaction, and extraction points.
Annotate your video with segment times to track improvement and to discover points for micro-optimizations.
Community tips (sourced from aggregate player strategies)
Many players recommend practicing the shaft skip repeatedly until it’s muscle memory—this is the single biggest speed optimization.
Coordinate a single “valve specialist” in co-op to handle interactions consistently.

FAQ
How do I find the valve in Switching The Supply?
The valve is in the Spaceport tunnels past a short corridor with overhead piping and a circular wheel. Use the vertical catwalk shaft shortcut to reach the valve room faster; it saves up to a minute on average.
Can I complete Switching The Supply solo?
Yes. Solo runs require a mobility-focused build and conservative valve defense. Prioritize quick stims and crowd-control tools. Expect to kite during waves if you lack team support.
Which mech loadout is best for speedruns?
A mobility-oriented pilot with a fast SMG or shotgun is ideal. Supplement with a dash cooldown mod and at least one EMP or AoE grenade to handle turrets and clustered enemies.
What to do if the valve interaction bugs out?
Leave the valve room and re-enter to reset the trigger. If that fails, abort the mission and restart—the trigger usually resets on mission reload.
Are there recommended settings for co-op runs?
Yes—assign clear roles (navigator, anchor, support), and enable voice comms. Have the anchor hold the valve while others cover flanks and clear spawn routes.
How much time can I realistically shave with practice?
With consistent runs and use of the shaft skip, expect to reduce run time by 30–90 seconds within a few practice runs. Advanced micro-optimizations can save more.
Closing strategy tips (fast wins)
Practice the shaft shortcut until it’s reflexive.
Coordinate one person to always start the valve; consistency reduces chaos.
Use the catwalks and vertical angles to take down ranged enemies quickly.
Conserve grenades for valve waves and turrets—not for early trash mobs.
