Tactical Ops: Assault on Terror

Like the popular Counter-Strike team-based shooter, Tactical Ops: Assault on Terror lets players assume the role of a terrorist or an anti-terrorist special forces soldier, and they must work with a team of other players in order to complete certain objectives, such as rescuing hostages, defending vessels, and capturing hideouts. In addition to the multiplayer mode, the game includes a complete single-player campaign.

This stand-alone game is based on a user-made counter terrorism mod for Unreal Tournament. It features more than 30 different maps, more than 20 real-world weapons, and 11 detailed character models and skins.
