In anticipation of the new Aliens vs Predator game by Sega, Rebellion has decided to rework the Classic 2000 game for modern computers. It contains only the singleplayer component, does not support widescreen or have any updated textures/models, but is only $5. Hopefully this will inspire AvP 2 to also be released as it was a much better game overall.
Edit:The Widescreen and FOV issues have been fixed and the multiplayer support has been enabled.
