TMNT: Out of the Shadows.
Was really excited for this for months beforehand, and being honest, I was disappointed, initially. However, I've played a bit more and it has improved quite dramatically. I can see why so many people have been dismissing it as slow and clunky...because the game starts you severely gimped. I think releasing a demo with the turtles at their most basic, un-upgraded state, was a terrible idea and will probably have put a lot of people off. Once you get up a few levels, you'll unlock a few extra things that make life a lot easier; particularly the 'Team' upgrades that improve your speed, toughness, attack strength, etc.
Of course, some of it depends on the enemy types (as Raph, too many of the early enemies are knocked over quite easily, making it difficult to maintain a combo) and learning the rhythm (can't attack relentlessly and then block at the last second like in the Arkham games, you have to anticipate enemy attacks because timing plays into whether you counter or just block/deflect). There's quite a bit of depth to the system and I can see myself really wanting to try and master it; I've already been stringing together 40+ hit combos, even with slower turtles like Raph and Donnie.
