Rampage through levels and shoot the alien scum in the face. Or behind, your choice. Eventually you’ll get yours kicked. Tough. Sucks to be you. But! With the loot you can find, you can get bigger and badder weapons that’ll leave a string of ruined enemies in their wake! By the end, there will be more bullet than air for everyone to breathe.
