You are trying to colonise planet Jamiro, but the alien race Jamirons have a solid defense and won't let you in easily. When you start the game, you enter your name, the other player's name, and amount of lives for both of you. After pressing start, you and the other player will be able to control the 2 main aliens whose goal is to dodge and shoot as many aliens as they can. Try to score the most points so you can get on the highscore board before you die.
As player1, you use the mouse to move your alien and the left click button to shoot. Player2 will use the WASD keys on the keyboard to move and space key to shoot.
