Sadly no Blood Dragons
Mark IV style mutha f*ckas!
Far Cry 3's map editor was just updated to include Blood Dragon's neon packed designs. This is just for the buildings and stuff, and doesn't include the creatures like the actual Blood Dragons. The update is available now for the Xbox 360 and PlayStation 3 versions, and we expect the PC version to get the update shortly as well.
The update is free, so you have no excuse to go make some crazy creations. Well other than you not owning Far Cry 3 itself. Which you really should go and get, cause it's a great game. As is Blood Dragon itself.
