Signature moves are the bread and butter of beat-'em-ups. Imagine Street Fighter with only Ken. You can't? Well Smash-Up will imagine it for you. Everyone fights at close quarters. Everyone has identical moves. Everyone has the same wall-jump – yes, the hulking Ultrominator is as nimble as a sewer rat. To top it off, they're all based on their universally rubbish modern cartoon iterations – dark and sleek, April and Casey may as well just be Foot Clan soldiers. Shredder and Karai are just Foot Clan soldiers. Four Turtles, five Foot Clan and a rat? Happy 25th anniversary, Turtles. You deserved better.
