Terrawars: New York Invasion is a sci-fi first-person shooter computer game developed by Ladyluck Digital Media, first released by Tri Synergy on June 28, 2006. Designed for PCs running on Microsoft Windows, the game uses the Lithtech Jupiter engine used in No One Lives Forever 2: A Spy in H.A.R.M.'s Way. The player assumes the role of John Armstrong, a medical student with the National Guard who must repel an alien invasion. The development team took about 5000 digital photos of Downtown New York City and used many references about Manhattan to replicate the real-life locations in-game.
