Hölle auf Erden (Hell on Earth) is a zombie supplement for Nuts! from Two Hour Wargames. It provides a simple Weird War 2 background to explain the alternate history for late in the war to allow zombies to be fielded.
It effectively adds some of All Things Zombie to the excellent Nuts! World War 2 rules which are based on Chain Reaction 2.0 which I reviewed back at the beginning of December.
Hell on Earth allows the zombies to be controlled or un-controlled and, as with All Things Zombie, the latter works well for solo play.
Hell on Earth is available in both .pdf and hardcopy formats at $5.00 and $8.00 respectively from Two Hour Wargames.
