Quick quest summary and objectives
Eyes in the Sky is a scavenger-style objective that requires installing multiple LiDAR scanners across a map and keeping them operational long enough to complete their data uplinks. The core tasks are:
Locate each LiDAR scanner spawn point on the chosen map.
Install the scanner (interaction time applies).
Defend or clear the surrounding area until the scanner finishes uplinking.
Repeat until required number of scanners are installed and uplinked.
Completing the quest contributes to progression, unlocks reputation rewards, and can be required for event or story progression. This guide details the three main maps where the quest commonly appears: Dam, Spaceport, and Buried City. For each, I list precise scanner spots and the fastest approach lines.
How to use this guide
Read the map-specific section for the map you’re on.
Pick a recommended loadout and role from the loadout section.
Run the step-by-step route listed under the map; it’s ordered for minimal backtracking.
If you’re solo, prioritize speed and stealth where possible. If in squad, assign roles (scanner, overwatch, clear lanes).
Use the FAQ near the end for common issues and fixes.
Rewards and why speed matters
Completing Eyes in the Sky often grants XP, reputation, and chance-based loot drops. Faster runs mean more runs per hour, which scales reputation and potential drops. Prioritizing uptime on scanners and minimizing fights increases runs/hour.
Benefits:
Higher run rate = more reputation, materials, and possible cosmetic drops.
Efficient runs reduce match time and exposure to high-difficulty enemy waves.
Squad coordination removes redundant checks and ensures scanner defense.
Recommended team composition and roles
Scanner installer: primary objective completer; should be mobile, durable, and able to finish interaction quickly.
Overwatch / Sniper: secures high ground, removes ranged threats, and interrupts enemy spawns before they reach scanner.
Runner / Roamer: clears new spawn lanes and retrieves powerups/health for the installer.
Tank / Crowd Control: holds choke points and uses AoE to stall waves during uplinks.
For solo runs, pick a hybrid loadout that balances mobility and survivability.
Recommended loadouts (general)
Mobility-focused: lightweight frame, sprint burst, movement augmentations; best for speedruns.
Defensive/support: shields, healing mods, and AoE stuns; best for holding scanners.
AoE clear: high-damage area weapons, grenades, and slow-debuffs; best for waves.
Utility: scanning tools, short-range recon, and gadgets that reveal or slow enemies.
Prioritize mods that reduce interaction time, improve sprint speed, and increase sprint-to-weapon swap time to minimize downtime when going between scanners.
How scanner mechanics work (short technical)
Interaction window: you must remain within the installation prompt until the scanner fully extracts — being interrupted resets or stalls progress.
Uplink time: each scanner has a fixed uplink timer; killing nearby enemies reduces interruption risk.
Destruction: scanners can be damaged by enemies. Some enemies target devices; place yourself to intercept those threats.
Respawns: once a scanner is installed and uplink completes, the next required scanner becomes active somewhere else on the map until objective count is met.
Efficient general tactics
Move in straight lines between scanner points; avoid circular or zig-zag routes.
Clear a small perimeter before initiating installation; a single enemy interrupt can waste the whole attempt.
Use verticality where available — high ground reduces surprise melee spawns.
Learn spawn patterns for each map; they’re consistent across runs.
If a scanner is contested, force the enemy away with an AoE or lure them into a choke where your team can ambush them.
Map walk-throughs and exact LiDAR scanner locations
Below are map-specific strategies, scanner locations, and fastest route suggestions. Each map section has a short 2–3 line actionable summary for quick use mid-run.
Dam — quick summary
Dam spawns scanners around structural chokepoints and near generator housings. Prioritize the Control Tower scanner first, then sweep the lower decks clockwise to catch spawns early.
Best solo route: Control Tower → Turbine Room → Overflow Catwalk → Lower Dock.
Best squad route: split into two teams (Tower + Outflow) and one roamer.
Dam: Control Tower (scanner 1)
Location: top of the Control Tower, near the communications array.
Approach: take the maintenance ladder up the east side; use the small catwalk to avoid the open stairwell.
Tip: clear tower windows before initiating; snipers spawn on the lower rim and will target the scanner.
Dam: Turbine Room (scanner 2)
Location: center floor between turbines; often behind a collapsed panel.
Approach: enter through the flooded corridor, hug the right-side walkway; the scanner sits near a yellow control panel.
Tip: enemies often flood from the turbine door; block the entrance with a deployable if available.
Dam: Overflow Catwalk (scanner 3)
Location: external catwalk over the overflow spillway.
Approach: drop down from the south parapet and hug the inner rail to avoid flanking spawns from the dam's outer ledges.
Tip: use vertical mobility (double-jump/dash) to quickly get back inside after scan.
Dam: Lower Dock (scanner 4)
Location: near the small boat slip and containers.
Approach: enter the dock from the long stair well; the scanner is tucked behind a chain-link fence.
Tip: clear container corners — melee ambushes are common.
Spaceport — quick summary
Spaceport maps scatter scanners across terminals and external launch catwalks. Use covered corridors to transition between points and control the high ground on the Terminal Roof.
Best solo route: Terminal Roof → East Launch Catwalk → Cargo Hold → Central Plaza.
Best squad route: two teams (Roof/Cargo) and one runner for the Plaza.
Spaceport: Terminal Roof (scanner 1)
Location: rooftop HVAC array near the satellite dish.
Approach: use the service elevator inside the Terminal; ascend to the roof and approach the scanner from the dish side to limit enemy spawn angles.
Tip: rooftop spawns often include flying drones; bring an anti-air weapon or burst explosives.
Spaceport: East Launch Catwalk (scanner 2)
Location: narrow catwalk leading to launchpad 3; scanner sits at the mid-span.
Approach: sprint across broken sections; avoid the gaps where enemies drop from above.
Tip: when the catwalk is busy, throw a stun to the far end to give yourself time to install.
Spaceport: Cargo Hold (scanner 3)
Location: stacked containers; scanner is inside a cargo bay with low lighting.
Approach: enter via the service hatch; proceed to the large container labeled “A-03”.
Tip: use flash grenades to reduce melee rushes from container aisles.
Spaceport: Central Plaza (scanner 4)
Location: near the central comm kiosk and fountain.
Approach: circle the plaza’s outer ring; scanners tend to be on the kiosk side facing the terminal doors.
Tip: altar spawns (heavy enemies) often come from the south corridor — check it first.
Buried City — quick summary
Buried City hides scanners in underground galleries, market ruins, and the Galleria rooftop. Use cover and vertical routes to avoid being funneled.
Best solo route: Market Ruins → Galleria Rooftop → Subway Entrance → High Plaza.
Best squad route: split into Roof + Market + Subway recon.
Buried City: Market Ruins (scanner 1)
Location: under the collapsed awnings by the broken stalls.
Approach: move along the vendor rows; the scanner is set into a stone pillar next to an overturned cart.
Tip: take the stalls slowly; explosive barrels are frequent and can interrupt installation.
Buried City: Galleria Rooftop (scanner 2)
Location: atop the central Galleria glass dome rim.
Approach: ascend via the staircases inside the mall; reach the rim and hug the inner glass edge.
Tip: rooftop snipers are common; bring a shield or a quick translocator.
Buried City: Subway Entrance (scanner 3)
Location: lower subway gate near the tracks; scanner is beside the ticket kiosk.
Approach: enter through the side service door to avoid train-borne spawns.
Tip: corridors funnel enemies; use a flash or smoke to buy installation time.
Buried City: High Plaza (scanner 4)
Location: the raised statue plaza overlooking the city ruins.
Approach: take the broken staircase and approach the statue base; the scanner hugs the statue’s shadow side.
Tip: watch for aerial spawns; vertical cover behind the statue reduces incoming fire.
Step-by-step route example (Best all-purpose run)
Use this checklist each run to minimize backtracking and downtime. This route assumes a 4-scanner requirement; adjust if the quest requires more.
Drop into spawn and move immediately to the nearest scanner on your map’s fastest route (Control Tower / Terminal Roof / Market Ruins) — this denies opponents early spawn control.
Clear a 180-degree perimeter around the scanner using quick bursts and grenades — don’t clear every nook, just the main approach lanes.
Begin installation; while installing, position a team member or deployable between the scanner and likely spawn lanes.
When uplink completes, immediately sprint to the next nearest point using the straight-line path. Use sprint-boost mods to cut seconds.
Repeat steps 2–4 until the required number of scanners are uplinked.
If contested, send a runner to flank while the installer holds; prioritize finishing the installation unless the scanner is being actively destroyed.
Once all scanners complete, fast-exit via the extraction point or linger for optional loot waves if you have time and resources.
Advanced techniques and tricks
Interaction queuing: if you know a scanner is nearly complete and enemies are approaching, start the install earlier to bait enemies into a kill zone.
Fake-out: drop a deployable or decoy near a scanner to draw enemy fire away from the device.
Vertical denial: when defending rooftop scanners, use cliffside positions where melee enemies must take damage to climb.
Resource pooling: coordinate with squad to set healing and ammo beacons near the last scanner to prepare for final waves.
Ping and mark: always ping scanner locations and likely spawn routes to keep the team informed.
Recommended weapons and gadgets
Primary: mid-to-long range rifle for overwatch (precision kills reduce long engagements).
Secondary: high-damage shotgun or SMG for close-range defense during installation.
Heavy: AoE launcher or flak cannon to clear waves quickly.
Gadget: deployable shield, stun grenades, or a portable beacon that draws enemy aggro.
If you want to focus purely on speed, consider a lightweight SMG plus a short-range shotgun to clear immediate threats and sprint between points.
Solo vs Squad: optimizations
Solo: avoid contested scanners. If multiple players converge, pick the one with the clearest perimeter first. Use mobility mods that reduce interaction times.
Duo: one teammate installs while the other overwatches and rotates to intercept spawn waves.
Four-player: split into install + clear + roam + overwatch. Two installers can alternate between points to cut installation time if the game allows concurrent installations.
Common problems and fixes
Scanner keeps getting destroyed: reposition to intercept enemy lanes and set a deployable between incoming spawns and the scanner.
Install keeps interrupting: increase your distance from obvious enemy spawn points and clear main approach lanes first.
Enemy spawns overwhelm: pause installation, back up, and clear the spawn lane then resume. Solo players should consider skipping a contested scanner to complete others first.
You can’t find the scanner: move to the nearest landmark listed in the map guides (towers, rooftops, docks). The scanner will be adjacent to those identifiable features.
Troubleshooting specific map issues
Dam: water platform glitches may hide a scanner behind debris; use the inner catwalk and crouch to look under ledges.
Spaceport: broken lighting can make the Cargo Hold scanner hard to spot; use your motion tracker or ping frequently.
Buried City: underground sections can spawn enemies from behind you; place a portable sensor pointed at corridors while installing.
Speedrun tips (shave 20–40% off your time)
Memorize spawn-to-scanner straight-line distances and practice sprinting along those vectors.
Use one consistent starting point and the same exit path to build muscle memory.
Time your installation: some players pause briefly right before the uplink finishes to get into a better position for the next run.
Prioritize scanner locations that are close together on the first half of the run; finish the farthest scanner last.
Use a mobility augment that reduces cooldowns on dash/jump to maintain momentum between installs.
How to maximize reputation and loot
Aim for perfect runs with minimal deaths — match survival correlates with higher potential rewards.
Finish extra optional waves only if your team is strong; inefficiency reduces runs/hour.
If the event or weekly challenge increases drop rates for quest completion, favor repeatable fast routes.
Playstyle variants (examples)
Aggro Control: You lead with an AoE weapon and force spawns into predictable lanes for teammates to finish. Best for teams with two support teammates.
Stealth Runner: For solo players who want quick installs without fighting, pick scanners in low-traffic spots and rely on mobility to avoid confrontation.
Brutal Defense: For high-difficulty rewards, turtle at each scanner, set traps, and force enemy waves to break on your team’s defenses.
FAQ
What is the minimum number of LiDAR scanners I need to install for Eyes in the Sky?
The number can vary by quest iteration, but typical runs require between 3–5 successful uplinks. Always check the quest tracker at mission start for the exact count.
What happens if a scanner is destroyed during uplink?
If a scanner is destroyed mid-uplink, you must install a new scanner at a different spawn point. Prioritize scanning the nearest available scanner to recover lost time.
Can multiple scanners be installed at once by different players?
Yes, if your squad spreads and installs different scanners concurrently you can cut total mission time. Coordinate to avoid overlapping defense responsibilities.
Which map is fastest for solo runs?
Dam is often fastest for solo runs due to compact spawn points and vertical shortcuts, but your mileage may vary based on playstyle and mobility mods.
Are there classes or subclasses that make this quest easier?
High-mobility subclasses with dash/jump resets and deployable shields make installation and defense much easier. Subclasses with AoE crowd control also improve uptime on scanners.
How do I handle the final wave after all scanners are installed?
Prepare a defensive position near the last scanner or the extraction point. Keep ammo and health reserves handy; have a teammate clear heavy spawns while others defend the objective.
Is there any RNG to scanner spawns?
Scanner spawn positions are consistent within each map but the exact selection may vary per run. Learning all possible spawn nodes and fastest path between them minimizes RNG impact.
Do enemies target scanners specifically?
Some enemy types prioritize devices and will attack scanners. Identify those enemy types quickly and intercept them before they reach devices.
