Favorite weapon? The Warthogs, man...the WARTHOGS!!! Roadkill buffet all around with extra crispy rubber tracks on the side and an earful of your commrades screaming at you on where you learned how to drive
Ah, but getting to handheld weapon machinery, I'd go with the riffle and the plasma guns as my preferred offense, but I usually rely on the melee attacks to save up on ammo (my father and my sister tend to run out in the most crucial situations several times)
