Alien Invasion
Your mission in this online strategy game is to face the onslaught of aliens and survive as long as you can. Use YOUR MOUSE to control the game. Move the mouse at the top of the screen, and the build panel will appear. Be sure to check in-game Help section for more info. My tip: Mine at the center of the map first, retreating as the game progresses so that you don't run out of mine sites very soon. Good luck!
