With yesterday's release of Wing Commander: Saga, we should also remind Wingnuts of the other great fan mods. Wing Commander Standoff, which finished its five episode release in August 2009, is a mod built on a heavily modified version of Wing Commander Secret Ops. Whereas Saga looks at the events following the Earth Defense Campaign and preceding Wing Commander III, Standoff looks at the Earth Defense Campaign itself from the end of the False Armistice to the Battles of Warsaw and Sirius, and the epic conclusions near Mars and Earth. So after you've enjoyed Saga be sure to also check out Standoff, if you haven't already!
Wingnuts can download both a Windows and Mac OS X version of Standoff from their Download page.
