Ubisoft's redonkulous Far Cry 3 spin-off Blood Dragon has shifted more than 500,000 copies in its first two months on sale.

The neon 1980s-themed reskin launched as a standalone download for PC, PlayStation 3 and Xbox 360 at the end of April.

Blood Dragon even helped drive sales of the main Far Cry 3 game, Ubisoft boss Yves Guillemot revealed the news to Eurogamer sister site GamesIndustry International.

Other "brand extensions" could also now be possible, he added.

"Blood Dragon condenses all the best bits of Far Cry 3, sprinkles them with cheesy nonsense and blazes its way through to a finale that will leave you grinning like a loon," Eurogamer's Dan Whitehead wrote in our 9/10 Far Cry 3: Blood Dragon review.

"I still don't really know what Blood Dragon is, or how it relates to Far Cry 3, but more to the point: I don't care."
