Hyper Iria (ハイパーイリア Haipa Iria , "Hyper Iria") is a cyberpunk action game loosely based on the anime Iria: Zeiram the Animation. The player gets to control a female mercenary named Iria. Flying can also lead to a miniature shoot 'em up stage with unlimited ammunition. Within the game, the object is to disable the security system with her gun, her fists, or her kicks. The default primary weapon is a laser pistol; when that runs out, the player can punch as well as kick. Kicking is considered to be the player's secondary weapon. Secondary weapons include flying bombs and grenades. Literacy in the Japanese language is required to fully understand the game.
In addition to security systems, there are also robots to deal damage to as the player attempts to make his way around a labyrinth-like military base in addition to an urban war zone. When the player dies, the countdown numbers on the continue screen are shown in traditional Japanese numerals (一, 二, 三) instead of the Arabic numerals used by the Western world (1, 2, 3).
