"Teenage Mutant Ninja Turtles: Smash-Up" on the PlayStation 2 (also available on the Nintendo Wii) is an action-packed 'Ninja Turtles' adventure that boasts a four player 2.5D fighting style, lots of environment interaction, and much more. This hot item shares many similarities with "Super Smash Bros. Brawl", featuring a whole slew of customizable battle options. The game also features several modes ranging from Arcade, Survival, Swap-Out, Battle Royal, Tournament, Mission Mode, and Practice.
'Smash-Up' is complete with a full ensemble of characters for your entertainment: April O'Neil, Casey Jones, the Ninja Foot Clan, Shredder, Fugitoid, Master Splinter, Karai, Raving Rabbid, Splinter Rabbid, Utrominator, Nightwatcher and, of course, our very own beloved ninja turtles -- Donatello, Raphael, Leonardo, and Michaelangelo -- are all here for a piece of the action in 'Smash-Up'.
At the moment, there are only two cheat codes available and they are for the purpose of unlocking alternate costumes, one is for Shredder and the other is for all four members of the Ninja Turtles themselves.
