Intruder is a stealth multiplayer experience, inspired by the great single-player campaigns of Metal Gear Solid, SWAT 3, Deus Ex, and Splinter Cell. The goal is to bring aspects of these games into the gameplay of Intruder, and turn it into a team-based multiplayer shooter. Intruder allows for stealth, teamwork, tactics, and environmental interactions never seen before in a multiplayer game.
