Query your cortical data node and you'll recall NeoTokyo was chosen along with 20 other titles for Steam Greenlight's second round of approvals back in October. The mod itself has been around for much longer, originally appearing in simple deathmatch form for Unreal Tournament 2004. Four years later it transitioned to the Source engine, where it languished without updates--until today, when developer Studio Radi-8 released a fresh version out of nowhere (which is apparently becoming a thing now), adding eight new maps and higher-quality weapon models.
The modes: deathmatch and Capture the Ghost (the latter, in a tip of the hat to NeoTokyo's inspiration from dystopian sci-fi anime classics such as Ghost in the Shell and Akira, replaces the flag with an android torso). The classes: Recon, Assault, and Support. Each brings special vision modes such as motion-tracking and infrared, and with the exception of the Support role, everyone can cloak for a short duration. Before each round, you select your primary weapon from an armory that grows as you gain rank from kills and victories. Think cyberpunk Counter-Strike.
It's quite the fun setup. The maps stick to the cyberpunk theme of dense city blocks, military installations, and industrial decay, with plenty of near-future gadgetry and set pieces of glowing computer interfaces and multi-legged tanks with scary-sounding Japanese names. Server selection is rather sparse at the moment, but it should hopefully jump up as word of the update spreads. You and your fellow operatives can get in the action by downloading NeoTokyo from its official website .
