My concept sketch of Barrel (The archetypal heavy weapons character)
Another concept for Barrel, later decided he looked more like an end of level boss.
Concept for Clip (Main protaganist)
Concept for a roll-away suitcase that opens into a guided turret. (bottom right)
Concept for a turret made from a reinforced camera tripod.
