Crash Dive!

Crash Dive! is a video game in the adventure genre and published by A.N.A.L.O.G. Computing originally released in 1984. It is currently playable on Atari 8-bit.

The player controls a crewman on the USS Sea Moss, a nuclear submarine patrolling the frigid waters of the North Atlantic. While performing routine maintenance, the player finds himself alive, alone, in a sealed hatch, following an underwater gas attack by a traitorous saboteur. The player's pyrrhic objective is to find and neutralize the saboteur and sink the ship to prevent an enemy power from retrieving its military and technological secrets. But the first problem is to survive to escape from the hatch to the gas-filled interior....

The game's interface is through a claustrophobic text window system not unlike Adventure International, with certain areas of the screen indicating the player's location, exits, inventory, and inputs. The player communicates with the computer using two-word VERB-NAME sentences. Although the interface is primitive, the game is more sophisticated than Moriarty's earlier Adventure in the Fifth Dimension, which was written in BASIC; this game employs machine language. Shortly thereafter, Moriarty would work at Infocom.

This game was published in issue 5 of A.N.A.L.L.O.G. Computing as typed code, and was inspired by the cover illustrations of an underwater arcade game that had long hung in the magazine's offices. The 'Feelies' pictured in the magazine helped in the solution of some of its puzzles.

It is possible that we have multiple downloads available when different versions exist.
