I played the multiplayer for about 2 hours tonight and once you get the hang of it, its pretty freaking awesome. I'm going to go ahead and say the freedom of movement displayed here for the shooter genre is pretty much revolutionary. The closest thing I can compare it to in some ways is descent but its actually more impressive than descent because not only can you fly around but you can drive around and run around.
Critics are always talking about "innovation" but their hypocrisy when they miss out on something is pretty blatant. If this was some other game other than a licensed transformers game, you would be hearing a lot more praise about this element of the game because its pretty much radically different than any other shooter out there. It just happens to be a transformers game. Now I'm not saying the rest of the MP is as revolutionary. The basic game modes are the same old same old. The weapons are nothing new. And the basic online structure is pretty much a COD rip. But god damn, I've never felt so free and able to move and do exactly what I want in a shooter game before when it comes to movement.
