Orius

Orius is the overseas release of Xexex, a 1991 side-scrolling shoot 'em up arcade game by Konami. It was renamed Orius in North America but kept its original title in other regions. The overseas versions introduce a variety of changes, with the most notable being the removal of all but one upgradable weapon, as well as the removal of a lives system, which is replaced with an energy bar. The enemy patterns are also changed slightly and the bosses have more health. Upon dying, the player starts where they died instead of going back to a checkpoint. The overseas versions also features two-player simultaneous co-operative play.

The game takes place in the far future, where mankind has recently developed technology allowing them to quickly travel to other planets. One day, Earth receives a telepathic distress call from Princess Irene La Tias (also known as Elaine La Tias), whose home planet E-Square has been taken over by Lord Klaus Pachelbel and his bio-mechanical army. Humans soon also discover the mysterious alien life form "Flint", and quickly assemble a new space fighter, the Flintlock TMF01, that is capable of carrying the Flint with it. The Flintlock and Flint are then sent out to save Irene and her planet.
