Foundation Armor is a Structure in Raft.


Used on any water-level structure, i.e. Foundations or Collection Nets, making them impervious to Shark attacks. Selecting it from the Hammer's build menu allows it to be placed on any already-existing foundation piece.

Armoring Foundations and Nets protects them from being attacked by the Shark. To fully protect the raft the player will need to armor the outer foundations only. This got changed with the Second Chapter, before the player had to armor the complete Raft. When armoring up the raft it is advised to first armor places supporting builds of high value to the player, such as Stairs, Walls with Storages or the Engines since removing a Foundation may destroy anything above it unless it has support from one of the adjacent Foundations.


  • Place on Foundations or Collection Nets to protect them from Shark attacks.


  • Before the Second Chapter the complete Raft had to be armored to be protected from the Shark. If inner foundations were not armored, the Shark would still attack them.
