Yup, all the reviews and ratings are correct. From the laggy and poor graphics to the waste of time and gray hair inducing multiplayer. This thing made me want to return it to the store and I only rented it! Horrible controls and even worse geometries mixed in with a game meant to be Coop based that lags more than a fat kid in a 5k marathon.
The AI is awful, kept getting stuck on walls and other characters. Game had so much potential, it felt like a rush job. Never finished the first level, i hate dit that much. Give it to a decent game company and let them fix it, Rockstar or Valve com to mind.
