John ran firing to the side as the aliens advanced firing back. He ran behind a tree and hid behind it. He checked the rounds in his UMPs' clips and cursed as he found them empty. Slinging them on his back and then unholstering his glock 45s he peeked around the side of the tree before exposing more of himself and squeezing 6 rounds off. John hid again waiting a little bit to pop out and continue firing. Little did he know that the weedy alien was in the tree above him.
