Into Oblivion

As with most titles in the genre, IO is a side-scrolling shooter that involves destroying alien forces in space. As the lone pilot of a missile-firing spaceship, your mission is to navigate through various alien bases while blasting everything in your path. Once the spaceship has been deployed from a floating base, you'll have three chances to foil the aliens' plans. Enemies include rival spaceships that attack in waves, ground-based turrets, and other advanced pieces of machinery. If the spaceship comes in contact with enemy fire or an alien, you'll lose a life. Extra lives can be earned by reaching a certain number of points. Because the action in IO is often relentless, there are items located in green tubes that will eradicate all aliens on the screen. Additionally, the game supports alternating players, so if one person is killed, the other will be offered a chance to crush the alien forces. Whether you're maneuvering through hostile alien bases or mysterious planets, the mission remains the same. Mankind is counting on your success.
