Errant Software has currently developed these titles:

"The Assassin's Guild" - 1996
Where it all began back in 1996.
A TEXT BASED game for MS-DOS. I didnt even bother to finish this one.

"Operation Condor" - 1997
My tribute to one of the best arcade machines of old - 'Operation Wolf'.
Also, this was my first attempt at using graphics. Programmed mainly in C, with some X86 Assembler used to quickly change registers on the VGA card.
Runs in MS-DOS.

UnNamed - 1998 (...in development...)
Ever wonder why the PC just doesnt have any good shooter games? Me too. I am trying to set that right with this project.
Full 3D, plenty of models, explosions, power-ups, and a kick-ass special weapon. Heavily inspired by such greats as Thunderforce V, Layer Section II and Radiant Silvergun.
Windows95/98 and Net Yaroze.
