Graphics::::::::::::::
Everything you see in the game looks like from the show. When characters attack in the game, it looks just like they attack in the show. The moves have been advanced and have better graphics and better effects, there is also more moves now. There is loads of new levels, and just like Half Life 2 and Metal Gear Solid 3, you can destory alot of stuff in the levels.
