OpenTyrian

And you thought being a Terraform Engineer would be easier than being a Space Marine? Blasting rocks to make way for new settlements on Tyrian seemed a quiet life, but your long-time Huzundra friend is now dead—bless his lizard hide. Murdered! And Microsol, the Terraforming company, wants you dead too! It's that huge new rock formation you and Bruce uncovered—it's called Gravitium, and it's priceless. Tyrian is the only planet where it exists in commercial quantities, and Microsol is determined to control it. You can expect them to throw all their resources against you, and they won't pull any punches. Strap into your Gencore Hawk fighter and try to remember all you learned as a Space Marine—you're going to need everything you have. With dynamite sound effects, music that will blow you away, unbelievable graphics, and weapons to die for—and to kill with! If Tyrian is more than your 10 trigger-happy fingers can handle, it's got TWO PLAYER MODE which allow you and a friend to gang up and blow away enemies. We told you this game is intense, so be prepared for some serious fun!
