Hull Rupture defense guide
Defense is a route problem and a gun problem. Aliens drop onto the outer hull and walk to the airlock. You see the landing time and the breach point before they arrive.
The 14 Sep 2026 update said turrets are first and meat shields are second. Cheat Code was weakened and turret-related artifacts were strengthened in that same note.
Four layers
| Layer | Job | Sources |
|---|---|---|
| Hull pieces | Lengthen the walk, especially toward the top-left boss drop | 1 source · Steam |
| Turrets | Main damage. Long range on open corners, short range in closed segments | 1 source · Steam |
| Airlock units | Last line inside the airlock. Fencers and Punishers are named | 1 source · Steam |
| Repair | Recover hull after a breach. Do not park it only at the stern | 1 source · Steam |
Placement from devlog 4
Long-range guns want open corners and exposed angles. Short-range guns want small closed segments. Drop pods land on most of the outer surface, top and bottom.
The boss always starts at the top-left, farthest from the airlock. Give that path length so more than one boss does not arrive together.
Turrets move for free, the move is slow, and the gun is offline during the move. In the demo, modules could not move. Reproducer's Eyes, a modifier on the Reproducer, adds Fragility to every Beam turret.
Damage, range, and fire-rate numbers are not in the public posts. Rocket, Shark, and Traps each have a single public source, so the turret table marks them as 1 source instead of a rank.
FAQ
Can I block the airlock with hull?
No. Hull pieces cannot cover the airlock or the engine.
Is there a best build?
There is a placement rule from the devlog. There is no damage chart to crown a turret.
What does the Rat turret do?
Added in demo v0.10.12. A hit turns the target into a rat. That is a status change, not a new enemy species.
