NEOTOKYO° is a first-person shooter total conversion modification of Half-Life 2 in a futuristic world setting, developed by STUDIO RADI-8. Initially released on July 3, 2009, it was voted to be released through Steam Greenlight on 16 October 2012. NEOTOKYO° uses a round-based structure similar to Counter-Strike, in which gameplay takes place in a series of several rounds. The game is class-based, with three classes available, each with slightly different characteristics, abilities, and available weaponry. NEOTOKYO° has two gametypes: team-based deathmatch, in which the team that manages to kill all members of the opposing team wins, and "Capture The Ghost", though the majority of maps are designed for the latter mode.
