Ocean

The Ocean is the body of water around the Peninsula, acting as the edge of the world and playing area. The player can swim or row a boat to the edge, but the player will take out a picture of Timmy and row backwards if they travel too far. After the alternative ending, the player will just hit an invisible wall.

Cannibals and most mutants cannot swim, though occasionally they can enter the water and not die. They can, however, walk a little distance into the water, although they will avoid further than waist deep. The animals that can swim are fish, sharks, turtles and crocodiles. The easiest way to travel at sea is by boating on a small raft, as it is currently the fastest and safest method. Sharks inhabit the water around the peninsula, and they can and will attack players who venture too close. Staying on a raft will protect the player from this, though sharks have been known to glitch through the bottom and eat the player regardless.

When in water the player can't attack animals/enemies, open the inventory or survival guide, carry logs or log sled, or do practically anything besides swim. The player can however place blueprints underwater, provided they were selected from the survival guide prior to entering the water. As of update v0.25, the ocean quality can be adjusted in the options menu (ocean quality can not be adjusted on PS4).
