Sub-Terrania is a classic 1994 multidirectional shooter game developed by Zyrinx. Taking place in the future, you are a lone pilot tasked to save a deep-space mining colony from an alien invasion. The game invites you to master the gravity-based controls of your rotatable craft, maneuvering through hazardous landscapes and combating alien forces. With your ship constantly subject to gravity and inertia, strategic refueling and efficient route planning become an integral part of the gameplay. The game also presents you with mission objectives, such as rescuing miners, collecting equipment and defeating alien bosses, all while keeping track of your fuel and damage levels. Despite its challenging gameplay, Sub-Terrania was praised for its originality, graphics, and soundtrack upon release.
