Survive on Raft strands players at sea on a small raft, where scavenging floating debris, building up the raft's structure, and managing hunger and thirst make up the core survival loop. Expanding the raft over time opens up new crafting options and storage space.

The open ocean setting keeps danger and scarcity constant, appealing to fans of survival games who enjoy the specific challenge of building a livable space from nothing while adrift.
