There is nothing really special about this game. A lot of people played it back during the 2011 holiday coal rush, and it barely had any players back then. I distinctly remember someone saying "thank God, now I never have to play this again" when they got their achievement. I think it had something to do with throwing snowballs around. It was kind of fun, but was definitely more fun than the vanilla gameplay this game had to offer, which is really bad.
Customization is there, but the quality of the models drops through the floor when you actually get in game. The gameplay does not consist of much more than running and gunning. The game just feels so empty. It starts off with a cool premise, and then forgets about it.
Free to play could not save this title. Steam coal rush could not save this title. I will leave it up to you to decide what that says about the game.
