Submariner

Submariner is a graphical text based adventure game played from a first person perspective. The game takes place aboard an abandoned submarine where the player is on a secret mission to obtain pictures of a weapon that is being developed on a remote island. The player's objectives are to find a camera, surface the submarine and leave it by climbing the exit ladder.

The player moves around the submarine with three commands: move forward (f), rotate right (r) and rotate left (l). Four commands can be used to interact with the environment: get, drop, open hatch, turn valve and climb. Get is used to pick up items and drop is used to remove them from the inventory since it only has space for two items. Opening a hatch requires having a crowbar in the inventory while moving in dark rooms requires a torch. Turning a valve requires a wrench and raises the submarine by 49 fathoms. To fully surface two valves have to be turned.
