OpenTyrian is a port of the DOS shoot-em-up Tyrian. Thanks to Jason Emery,
the developers were given a copy of the Tyrian source to port but
not redistribute. That code has since been ported from Turbo Pascal to C
using SDL, making it easily cross-platform. The 'Classic' port involves
minimal changes, but the 'Enhanced' port will feature further development.
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.
