It was a decent concept ruined by technical execution. On the PC side the matchmaking was crap, and pretty much killed the game. There are maybe 500 people at the most that play it. No server browser, no dedicated servers, and no options, was the death of it on PC. Who wants to play a multiplayer game where you can't even do something as simple as select which map you want to play?
For some idiotic reason I got suckered in to the hype and got the season pass. The game is so dead, and without the ability to select maps to play on, there are a few maps from the various expansions that I just never had the patience or will to keep playing to see.
Overall a very shitty port to PC, and I will never buy another game from them again.
