Atomaders

Atomaders is a Space Invaders style game that puts you in a fighter ship on a mission to defeat wave after wave of alien attackers. There's no real plot to this game, just progressively harder waves of aliens and different backdrops to do battle in. You can gain bonus weapons, such as curving missiles, a powerful laser, and the all mighty crusher, by collecting items that fall from the defeated enemies. You also have to avoid asteroids and fight giant boss enemies on several different planets. All with the control of your mouse, keyboard, or gamepad. Each planet is divided up into 12 levels, with a bonus level every 5th level, and a boss at the final level. And each also provides a new enemy type and weapon to battle and earn respectively.
