One of the most fun multiplayer games I've ever played, tons of free content constantly being added, awesome devs that communicate with the community constantly.

The creators are adding new content and patches regularly, and it's improving all the time.

My only major gripe is they need to fix the bugs and add some more content, like a single player mode

If they weren’t complaining about the release date being pushed, they were complaining about not being able to get a pre-order skin, or the servers crashing on launch(this happens to every Call of Duty game with their budget being extravagantly more), or that content would be available in increments
