Aurail is a scrolling shoot 'em up arcade game developed by Westone and released by Sega in 1990.

The player pilots a tank mecha and shoots enemies (it can fire in 8 directions), collects power-ups to increase shields, operates the remote attack drone, and defeats bosses to advance levels.

Enemies can also leave a green "D"-power up, which summons a robotic orb which will accompany the tank until the next life loss.

Westone's PC Engine/TurboGrafx-16 game Blood Gear (1994) identifies itself as "Aurail Scenario 2" in the ending credits.

The game also contains artifacts and references to Aurail as a lost civilization, but Westone co-founder Ryuichi Nishizawa has stated in an interview, that Blood Gear is not a sequel.
