Commando lvl 50. I use the Minigun, P99, Ammo Feed, and the Bouncing Betty. I may sometimes use the Commado(gun), Desert Eagle, Matyrdom, and Air Strike. So the answer to the question is obviously commado.
hears a neat little secret there is no best character because each level has a paticular character that is best for example in the vilage level the assasian with sniper rifle and in the air plane tank and in the lab medic.Its a combanation of factors that make each character best in whatever paticular level
