Crusader: No Remorse is on sale at GOG.com for $5.99! Pick it up DRM-free here.
Their extras are sorely lacking currently, but hopefully in the future they will add our site’s contents for download. I’ve been in contact with GOG regarding the extras and it is currently awaiting approval from EA.
Edit 6/10: The Wing Commander CIC has celebrated the release of No Remorse on GOG with “Crusader Day.” Check it out!
