Terrawars: NY Invasion

About

Terrawars: NY Invasion is a budget-priced first-person shooter that takes place in an alien-infested New York City. You play as John Armstrong, a medical student that's been drafted into the Army National Guard to fight the aliens. The game plays in standard first-person shooter fashion: Move through the level, kill all the aliens, and try not to get killed by them. In some levels, you'll meet allies who will fight the aliens alongside you.
