Guns

"The world of Dead Matter is filled with every manner of weapon you could think of, and we've built them from the ground up to support all kinds of personalization. Whether you want to wrap your baseball bat in barbed wire and go out bashing, rig an alarm clock with C4 to go off with a bang, or strap up your gun with a makeshift kitchen knife bayonet, the choice is yours."
