A rare French arcade game in which you play as divers and fight with other hostile divers and various sea animals and monsters in the depths of the sea. There is no plot, which is very good.

Your weapon is an underwater harpoon gun with a very good rate of fire and infinite ammunition, which is good, given the number of opponents and their endurance. Enemies are represented by sharks and other large and small vicious fishes, octopuses, squid, sea snakes and some kind of surreal creatures, as well as, as already mentioned, other divers. Any direct contact with any enemy instantly leads to death. Even at the very bottom of the sea there are mines that begin to rise if you swim close to them (it is strongly not recommended to do this).
