In 2010, the game was ported to J2ME/BREW mobile phones, Windows Mobile and iOS platforms to coincide with the release of the remake. The only change was in the Java-based mobile phone version, where Rick's mask is modeled after the skull-like one present in the remake. This change is not present in iOS version of the game, but it includes a "Splatter Rush" mode instead, where enemies continuously spawn from both ends of a wide screen. The remake also included the uncensored Japanese arcade version as an unlockable extra.
