It was almost perfect. Everything in the game is good, it's like a cross between COD zombies and The Walking Dead. The only let down was the same thing in most FPS games the inertia of the controls was a little too fast. You can't just slow down the controls it's the programming, COD has got it right most of the time but if it had that feeling when looking / turning then it would be perfect.
The adventure aspect like an episode of walking dead was really good.
