Teenage Mutant Ninja Turtles: Tournament Fighters (SNES)
Teenage Mutant Ninja Turtles: Tournament Fighters is a traditional 2D fighting game similar in style to Super Street Fighter II and various other SNK and Capcom games released around the same period. It was not terribly successful upon release, but over the years, many devout fighting game enthusiasts have come to appreciate it, with some tournaments being held, mostly at the local level.
The SNES version of the game employs a very simple Fatal Fury-style LP, HP, LK, HK button setup, that being Y, X, B, and A resectively (on default control settings). As the players engage in battle, a 'special' meter charges, just below the energy bar. Once the Super meter is filled and begins flashing, holding down HP + HK in unison will release the special technique. Many of these techniques are extremely powerful even when blocked and have the ability to strongly effect the outcome of a match. When evaded, they can often leave the player who initiated them vulnerable, however, so these should be used with caution (on a character by character basis, obviously).
Each character has their own set of unique special moves, executed with various combinations of directional and button input, but only the Ninja Turtles themselves all possess the ability to backflip out of harm's way by tapping <-- twice rapidly. This gives the turtles a solid escape strategy that is good for evading cross-ups and some projectiles.
