OpenTyrian is a port of the DOS shoot-em-up Tyrian. Tyrian is an arcade-style vertical scrolling shooter. The story is set in 20,031 where you play as Trent Hawkins, a skilled fighter-pilot employed to fight Microsol and save the galaxy. This port is done by Molokai.

Changes:

– Impossible, Suicide, and Lord of Game difficulties now available by default in difficulty select menu.
– Change in onscreen keyboard startup and shutdown routine. Result is an increase in speed when loading the save/highscore name entry screens.
– Rich mode (a.k.a. loot) now accessible through “OpenTyrian” menu option.
– Latest changelog now included in meta.xml (for the benefit of the HBB users).
– Special Games/Modes menu added. Access by simultaneously pressing left and right sidekick assigned joystick buttons (or F15 on a keyboard, if you have one that far up). Includes choices for both Arcade ships (i.e. UNKNOWN, WEIRD, NORTSHIP, etc), as well as the two difficulty settings for ENGAGE (suicide and LOG). Will eventually include Destruct mode (2D tanks game), but since it’s not rigged to work with joysticks at the moment, it’s useless on the Wii.
