If the singly player ends with an impressive "whoa," the multiplayer and co-op begin with a resounding "oh no." Because for as good as the short-lived single player is, the bits where you need to connect through game servers is a bit of a mess right now. First of all, content is a little light. There is only a single Zombies map and eight or so multiplayer maps at launch. Surely, this will expand over time with seasons and DLC, but there really isn't much more variety than what was on offer with the Beta at this point. In-game it all plays how you would expect a Call of Duty game to play. It's a fast-paced, rather linear twitch shooter with at least one juvenile in every match with his mic constantly on blasting the conversations and background music to every other member of their household ad nauseam.
