Fast, Low-Risk Cluster Clear (Smoke + EMP)

Build a cheap forward line: short wall posts + sandbags, ~25–30 tiles from the cluster edge.
Send 1–2 smokers to keep a continuous smoke lane between turrets and your shooters.
Walk an EMP thrower inside the smoke and stun the first mechs/turrets that wake.
Delete high-value buildings first (shield/assembler/activator), then clean turrets safely.
If it spikes: smoke → fall back → tend → re-engage when everyone can shoot again.

Tip: This page focuses on the safest universal play pattern; exact cluster parts vary by DLC and storyteller.

What Wakes a Cluster (Rules of Thumb)

Assume any direct damage to a mech or cluster building can wake the whole cluster.
Proximity/countdown parts (if present) exist specifically to force activation—treat them as priority targets.
When in doubt: approach under smoke, keep your team grouped, and fight from cover.

If you want exact numbers for your version, use the in-game Inspect pane and the wiki pages linked in the Data tab.

Role Checklist

Smoke/Screen: Smoke launcher + extra shells; refresh smoke before it breaks.
EMP Control: EMP grenades (or EMP launcher) to stop pushes and disable turrets.
Long Rifle: Sniper rifle or bolt-action to pick priority buildings when safe.
Turret Killer: high DPS gun (charge rifle/LMG) to delete turrets once blinded.
Shielded Breach: meds + melee to finish buildings quickly if you must step in.

Early game: smoke + EMP matters more than having “perfect” guns.
