Players control the Mad Devils, a squad of elite soldiers sent on a mission to stop the maniacal Major Strauss and foil his plans to summon an army of demons to turn the tide of World War II against the Allies. They have failed. Dead, defeated and damned, they regroup in the underworld to close the demon portal on the other side and save the world. Mad Devils can be played solo with an AI partner or co-op, online or locally, with players building and controlling a six-member Mad Devils team. Demolitionists, snipers, commandos and many more, these hell-mutilated heroes fight with hellish firearms and new-found demonic forces against the inhabitants of hell and a battalion of damned Nazi soldiers.
