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 Roy Gillotti.

Changes:

Realized PND was poorly optimized causing lag on Rebirth and CC units: should now be playable on all units at 600Mhz. May have also fixed odd issue with prior save games being wiped out.
