The multiplayer is unplayable. None of the guns are balanced camping is key, and the random spread even when aimed down sights makes engaging at range difficult and annoying not even taking into account the net code issues that can send rounds off at 45 degree angles.
The zombies is fun but the weapons feel underpowered excluding shotguns which shred entire hoards in a few shots. As well the weapon tier upgrading is both difficult to do in the middle of combat and you can only see the salvage in a menu. Not To mention that getting weapons in a round is useless as the one you bring in will be the best. Honestly I would have rather spent $60 to buy a zombies mode for modern warfare.
