Mariner

Players pilot spacecraft in Mariner, a horizontal shooter released by Amenip in 1981. This cooperative game for two players tasks them with navigating through underwater environments and confronting various obstacles while progressing through levels. The gameplay involves maneuvering the ships to avoid hazards and defeat enemies encountered along the way. Mariner is an export release developed in the United States, originally known as "800 Fathoms." A unique characteristic of the game's initial run is that all high score rankings begin at a default value of 10,000 points when first played. The game’s design reflects a shooter experience centered around teamwork and shared objectives.
