Love this game SO much! Game heavily encourages team work with each of four different classes complementing each others's abilities, dozens of different enemies with unique abilities to master against, several gamemodes and randomly generated level types to play on, tons of different modifications for your arsenal on each class, a bunch of cosmetics to bedazzle your dwarvern characters, and best of all: BEER!
Extremely recommend for anyone who loves games with the randomly generated spelunking elements of Minecraft and/or the 4 player coop wave sweeper elements of Left 4 Dead. It's awesome!!
