Blackthorne is an early Blizzard game, first released on the Super Nintendo in 1994.
The game is a mixture of platforming (very much in a similar vein to Prince of Persia – style of climbing and jumping), and run-and-gun shooter.
The graphics are a little dated, and the gameplay a mite unforgiving, but Blackthorne is still a worthy of a play today.
