A series of first-person shooters that eschews the narrative, scripting and free-roaming advances introduced to the genre by such titles as Half-Life (1998), Medal of Honor (1999), Deus Ex (2000), Halo (2001), and the Call of Duty and Far Cry series, and carries on the tradition of Wolfenstein 3D and Doom of 100% pure, unadulterated, balls-to-the-wall in-your-face shooting action.
