Personally I really love this game. It's got the right amount of depth I'm after, and it seems more about skill than other FPS games. As in there's no super gun or items. Currently I'm hitting the top of games just using the standard rebel rifle, the thermal grenade, and the jetpack. I don't use any other items. But! It was fun getting to this point because the balance between being a newcomer and capable is really thin.
Did you buy the season pass ?
