Well it's an open world FPS without Masterchief and with more tactical elements. Doesn't sound like Halo to me.

 So...its a Metroid Prime rip off? I dont know much of the game so correct me if im worng.

Haven't played a 3D Metroid game, so I can't answer that correctly. I keep hearing Metroid Prime games are First Person Action Adventures, so I guess it's not a rip off, because I'm sure ODST will be a 100% FPS
