About Aster

Aster is an arcade-style shooter set during Earth's losing war against aliens from another galaxy. You play as an ace mercenary pilot hired by Earth's military to turn the tide, fighting through 38 levels to protect Earth from the alien threat.

You upgrade your ship and improve your piloting skills as you battle your way through space.
