You must clear a path back to Earth. Once the path is clear our fleets can warp home to reclaim Earth. Strike of the Centurion is an asteroids/star control inspired shooter. You must clear all asteroids to finish each level or fight to the death in survival mode. You can customize your ship to fight in the way that best suits your style. There are 3 main weapons types and lots of extra's like shields, missiles and point defense. Most items have multiple levels of power. There are cloaked enemies. Enemy units do not have health bars since the damaged units will change visually to show how much health each has left. Watch out for the wide selection of enemy space leeches that like to attach to your ship. This has been a one man project for the last seven years to put everything I ever wanted into an asteroids type game. I created this game using the allegro library. I learned of allegro from the book 2D game programming all in one.
You can play up to mission 12 or for 12 minutes into the survival mode game. Once you reach level 12 the game will basically kill you off. If you live long enough to make it to 12 minutes in survival mode you will also be killed off. You can play the levels all you want. The 12 minute limit is on each attempt not a cumulative timer. If any bugs are found please let me know.
