(’92) Appearing exclusively on the Sega Genesis, The Hyperstone Heist’s gameplay differed little from TMNT IV’s, though it offered a fresh new adventure.
As Manhattan mysteriously disappears, the Turtles find it to be the work of Shredder, using his newly acquired Hyperstones as acts of terrorism. Once again they must track and defeat their arch nemesis, having to confront Krang and his right-hand man, Tatsu.

(’93) Playing off the tournament fighter mode originally built into TMNT IV, Tournament Fighters successfully delves far deeper into the fighting genre. Everything you would expect from a Capcom Street Fighter game is here. Tournament Fighters appeared on the NES and SNES as well, but all three versions differ somewhat in plot and characters.
As four evil Turtle clones kidnap Splinter, Krang issues the Turtles a challenge to confront him in a tournament of sorts in Dimension X.
