I dont know what this game needs but they can’t leave this game to die, the level design is some of the best I’ve ever seen. Also the world they’ve built is simply incredible.
Maybe have Steam Works integration and Achievements that would entice players to play more.
Also what about giving this great game a make over like the Secret World and remove the targeting system so its free targets. I know its had a make over once before but the levels and world is simply intoxicating.
