Tubular Worlds is a side scrolling shoot 'em up game featuring pretty good graphics, a variety of weapons and enemies, great sound but rather repetitive gameplay. It is available on the Amiga (OCS / ECS / AGA) and DOS systems.

STORY / GAMEPLAY As a Cyber-Legion cadet you're now ready for your final exam and aim to succeed. You must fly through four virtual areas of the challenging "Tubular Worlds" military simulation and earn the right to join the elite ranks of the empire's battle fleet. You have to blast your way through the enemies to survive and get power-ups and weaponry upgrades by killing the enemies, which will help you reach your goal. The game is quite difficult sometimes, as except of the enemy ships and ground-to-air defenses you must avoid hitting a variety of obstacles like the top of rocky mountains.
GRAPHICS / SOUND The game features nice visuals. The backgrounds are nothing to complain about or to get overly excited, for that matter. The game's color palette is appealing while the sprites and backdrops move fast and smooth. The controls are very responsive and very easy to learn. The differences between the Amiga OCS/ECS and AGA versions are minor, and can only be spotted in some small details at the backgrounds, and the number of colors on-screen. Tubular Worlds' sound is quite effective an consists of decent sound effects and in-game music while there is also a brief intro sequence before getting into battle.
