Counter-Strike NEO (Japanese: カウンターストライク ネオ, Kauntāsutoraiku neo) is a Japanese arcade adaptation of Counter-Strike, the original Half-Life multiplayer modification. It was published by Namco and runs on a Linux system. The game features unique maps, factions, and settings, though the gameplay and the weapon lineups remain the same as other Counter-Strike games, only with a huge difference in visuals.

Along with NEO, there were several Flash visual novels spin-offs set within the same setting made by developer Romancework, titled Counter-Strike NEO -WHITE MEMORIES-. The visual novels have a continuing storyline and even some portions that loosely resemble Counter-Strike gameplay. Download them by accessing the Gallery below.
