NeoTokyo (stylized as NEOTOKYO°) is a multiplayer tactical first-person shooter total conversion modification of Half-Life 2 in a futuristic cyberpunk setting, created by American developer Studio Radi-8.

The game presents itself in a dystopian setting, with inspiration drawn from Akira, Deus Ex and Ghost in the Shell for its art-style, music and aesthetics.

The gameplay of NeoTokyo is slow-paced and balanced towards the tactical approach, with players generally being able to dispose of each other with a single burst of concentrated fire.

NeoTokyo has two game-types: Team Deathmatch (TDM), and Capture The Ghost (CTG), with the majority of maps designed for the latter.

With the Ghost's exact location visible to everyone at all times, a carrier's position is instantly revealed to the enemy team.

[1] In response, the Prime Minister of Japan pools former military intelligence operatives and police officers into a sub-group of the Interior Ministry's National Security Force (NSF), called Group Six, to seek out subsequent coup plotters and uphold the law in both domestic and international soil.

[2] Immediately, rumours surface that an unknown faction in the JGSDF's special forces unit "Jinrai" is preparing for another coup attempt against the government.

Ghost in the Shell and Akira were cited as main sources of inspiration behind the game's art style and cyberpunk aesthetic.

[4][5] The soundtrack of NeoTokyo was composed by Ed Harrison, and was described as "haunting" by Jeff Fleming of Game Set Watch.
