The spaceship “Triant II”, carrying an all-female crew under the command of Rachel Hugett, was attacked by mysterious aliens. The captain ordered to fire the strongest weapons, but nothing could help: the aliens invaded the ship…
...and in a unique twist, the player has to control an alien. No information is given about this playable character, that looks like a red crab. It starts at level 1, at the point where it invaded the ship. The game plays like a first-person dungeon crawler (this time the word “crawler” taken quite literally!). The alien moves through the pseudo-3D corridors of the ship. Crew members, robots and machines appear randomly and try to stop it. The battles are turn-based. The alien has two primary kinds of attacks at its disposal: physical attack (with its claw), and electricity attack. Defeating enemies brings experience points, leveling up the creature.
