Create a basement under your base for an extra layer of protection and increased building area!
How to build
- Have at least one Square Stone Foundation — the basement option appears in the Tool Cupboard UI
- Use a Hammer to place your first basement entrance
- You now have a 1×1 Basement
- Inside, use a Jackhammer on the walls to expand into cells beneath valid foundations
Build costs
Entrance 420 HQM | New cell (square) 25,000 Stones | New cell (triangle) 12,500 Stones |
* No upkeep costs currently — this may change in a future update.
When a basement is destroyed
❌ All entrances are destroyed
❌ The foundation above a cell is destroyed — that cell goes with it
❌ Containers and deployables float to the surface and are destroyed
❌ Players inside are killed and their bodies float up
Can players damage the walls?
✅ Exterior walls are indestructible — only destroyed entrances or foundations above can bring them down
