Waste.

The gun power ups dont really help any. You figure buying a bazooka would be more powerful but its very slow firing and still takes multiple hits to kill. The auto pick up automatically switches your weapon you just picked up to your active weapon meaning your constantly having to stop, switch back to your machine gun from that other crappy gun you picked up and carry on for another 5 seconds before you do it again. Bad game, dont bother

Fisheeeeeeeeeee about Desert Slug, v1.5
