Mad Devils — when World War II enters its final stage, the fascist war machine resorts to the occult to turn the tide. The manic Major Strauss plans to open the gates to hell itself, and an elite team of Mad Devils is deployed to thwart his plans. Dead, defeated and damned, insane devils regroup in the lower world and try to find a way by which they will be able to close the gate on the other side. 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.
