YMMV / SS Doomtrooper

• Complete Monster: Dr. Ullman is a geneticist making Super Soldiers for the Third Reich. To do so, he painfully experiments on dozens of people and animals, shooting down 17 Allied planes to protect his operation and eventually siccing his Doomtrooper on the French Resistance when he succeeds. When Captain Jerry Malloy is tasked with leading a covert operation to stop Ullman, he unleashes his monster once again, not caring when it massacres his fellow German soldiers. His boss tries to shut the experiments down, so he kills him and has several soldiers strapped down to become more Doomtroopers, ordering the previous one to slaughter the entire base when he's thwarted.
• Spiritual Adaptation: It's basically Return to Castle Wolfenstein but starring a group of Action Survivor and set during the war instead of before.
