A crappy game not worth $20
Alien shooter is an arcade shooter in the 3/4 perspective. You can chose between a male or female character though the differences are minor as the game focuses on sending swarms after you. That means your going to stand in certain area's and lure enemies out to kill them. At first the game seams fair and easy though in the third level and beyond, it starts setting up cheap ambushes where you can easily die if you don't have the right guns equipped. The surprised ambushes feel cheap as they can surround you and shoot acid at you. It's an artificial way of making the game harder that dulls the experience. It gets worse as you go along where you need to buy the newest gun you can for every level to stand a fair chance. The buy system feels more like another obstacle rather then a tool. I became annoyed that I didn't want to play it anymore
