Still keeping this alive, still have moar ideas:
Vehicle: Light Tank
Into: Just Cause 2
Specials: Incredible Acceration, and mass. Can ram a Taxi without even hint of slowing down. It can shoot Swarm Seekers, which comunicate with each other and with each missile updating the targets position every 1/8 of a second, you WILL hit your target.
Weapons: Every planned weapon in Modification Discussion (Zloff, Acturus, GCat, Takato, etc.)
Into: Just Cause 2, Uncharted 1, 2, and 3, CoD:MW 1, 2, and 3, Killzone 3, Army of Two.
Specials: All weapons would work in those listed games just like they would if the programers made them, but the models and animations stay the same.
