Tube Panic

Tube Panic takes the player into a strange futuristic 3-D world, where space battles are fought inside huge, geometrical arenas swarming with mechanical hordes. Equipped with a beam cannon to shoot its way through the waves of enemy battle groups, the player's ship moves continuously forward along the structures' walls, with the camera behind; the view shifts and rotates along with the ship.

Travel can be sped up or slowed down, but the ship's power drains at a constant rate - losing it completely will disable your guns. Power can only be recharged by successfully docking with the mothership at the end of each mission, which also awards a score bonus. In the game world's many tubular sections you will encounter indestructible roadblocks, armored mini-bosses, and the occasional "warp holes" (which safely transport your ship some distance ahead).
