Operation SpaceHog - Version 1.0 Spacehog is a horizontal scrolling shoot'em up game for one or two players. If you ever played Gradius on Nintendo or Project X on the Amiga you'll know what it's all about. The player gets to control a small ship in a battle against horrible odds. Luckily the player can pickup power-ups along the way and upgrade the ship with these. The nature of the power-ups vary from ship-manuverability to hightech weapons and shields.
