Bionoids is a game of defense and action. You have many weapons from which to choose and can get more through game play or buying upgrades. You can also purchase upgrades for armor as well. Special abilities can be used by pressing X and the mouse will aim and shoot your weapon of choice. You're competing for the rank of Master of War against three other contenders. You have a unit of Bionoids that you must control. If your unit wins, they will become part of the alien forces. Start by using the training mode to get the feel of the game and then move on to some real action and adventure in Bionoids!
