Deep Abyss is one of the first Sony Ericsson games released. It was produced in 2002, and it belongs to the platformer genre. The player controls a man on a mission to collect crystals in an underground volcanic maze. The spelunker can run, jump and, starting from level 4, equip a parachute and skydive. Dangers include lava, sharp rock formations, and falling from too high. Each of the fifteen levels require a certain number of crystals to be collected in order to finish the maze. Beside collecting the minimum number of crystals, the player may collect all the crystals in the level, resulting in a "Perfect" score for the level. Although there is no classical arcade-style time limit, latter levels gradually fill up with lava, forcing the player to hurry towards higher sections of the level.
