It's got it's flaws, but I think the game got severely shafted by releasing during the height of Payday 2 and players expecting Payday 2 gameplay but with a WW2 skin. Additionally if the latest news from the patch notes are to go by, the devs themselves are shafted by not having full source code access to diesel, so they're only able to do so much with the game. Personally I would recommend getting it during one of the yearly sales.

RAID!!!
