a playstation 2 (ps2) remake of the game was released in 2004 in the uk and the us and kor with more detailed polygons and textures, higher difficulty, redone voice acting and an additional mission taking place six months after the crisis zone arcade mode. the ps2 port is compatible with the guncon (g-con 45 in europe) and guncon 2 lightgun, and is available with an unusual two-player cooperative gameplay mode named "two-gun mode" by allowing two players to play simultaneously on a single-player mode without the use of split-screen, or weapon switching system (similar to time crisis 3, with some changes) allowing the player to switch between a fully automatic machine gun, a standard 8-round handgun and a 6-shell shotgun, depending on settings. unlike "time crisis 3" and "time crisis 4", where only the handgun has unlimited ammunition and other weapons are replenished by shooting certain enemies, all weapons now have unlimited ammunition in "crisis zone", though they all must be reloaded. as with the playstation 2 version of "time crisis ii" and "time crisis 3", players can access the crisis mission exercise menu through prolonged gameplay. the us and kor version of the ps2 remake is called time crisis: crisis zone.
