Metroid is as classic as they come and Metroid Genesis pays tribute to the awesomeness that is/was Metroid. Controlling the game is simple. Use the mouse to aim, and left click when you're ready to shoot. If something attaches itself to you, then hit the space bar to knock it off. Your visibility is reduced as you take damage so you have to shoot health orbs in order to keep from going blind, or dying. In order to complete each level, you have to kill everything that comes at you. If you've enjoyed Metroid in the past, you're going to love this version.
