From the campaign:
Drive Them Back is a semi co-op card game for two to four players. You compete to be the most Epic Hero of the game while working with your friends to keep the enemy formation from getting too large. Inspired by hack 'n slash video games, each player wields an over-the-top weapon and the more enemies you defeat, the more Epic Attacks you can unleash! Epic attacks range from a hail of axes, giant tenderizers, a cyclone of saw blades, death itself, and even the mightiest of sea creatures!
