Title: "They did it."
You start off as a naive young man just graduating from high school in the summer of '41; and you join the Waffen SS because you believe in National Socialism and think Hitler is great [When you were a kid, your family had no food so you knew starvation and saw your parents starve; then Hitler came to power in '33 and your father had a job, and then your family had food to eat].
Part I You are sent to the Eastern Front, you get to shoot a lot of bullets and kill a lot of Russians, as part of a Forward Recon squad. Like the movie "Cross of Iron" (1977). You have to make moral and political choices on killing women and children; rounding up Jews; looting; shooting informers, etc...
Part II When you get "seriously wounded and falls unconcious" at Battle of Moscow, you will be taken to a hospital in Poland. Where you befriends a girl from a rich aristocratic Prussian family, you play several non-shooting missions where fate keeps throwing you two together. She hates you but falls in love with you, and as the player you decide whether your character loves her or not.
Then you get a few missions where you go around Warsaw and play detective against the Polish resistance; also some interluding missions where you and your wounded comrades can commit atrocities in Concentration camps, how will you respond if you are forced to lead people into gas chambers (you get paid overtime for it)?
Through these Polish missions you have the option of probing into your girlfriend's identity, if you probe hard enough then you discover her father was the illegitimate child of a Jewish maid, but since he lived while his brother died in infancy, so their ID was switched. You can then choose to protect her at all costs, or do nothing, or expose her, or some other option in between these 3 extremes. But very soon after you discover (or not) her identity, you are sent back to the front.
part III Escape from the encirclement of Stalingrad, all the horrors of war, scorched earth, etc. Battle of Khakiv, comradeship among the SS men, like "Band of Brothers", only more so; your comrades who commited various atrocities really do care for you, and saves your life... News from Warsaw that your girlfriend (the aristocratic girl) has been arrested...
Part IV You go back to Berlin to receive the Knights Cross, and get some R&R time. Your SS comrades persuade you to forget about the Jewish girl, and you meet some German girls (various political and family) backgrounds, and there are some choices to be made here.
Part V Western front. (Or you can choose to stay in Berlin with your new German wife) You get to shoot and kill a lot of soldiers again, this time the Americans. Only your unit has hardly enough supplies to feed itself, so what will you do about the American POWs you capture? You get to be part of "Kampfgruppe Peiper", the best armoured unit in the world, only this unit has no fuel, so it gets surrounded, and you run for your life. But do you really want to go back to Nazi Germany? Or have you seen enough of the war that you surrender?
Part VI The last Battle. If you go back to (or stayed in) Germany, you are re-assigned to the Polish front to defend Berlin against the Soviets. Will you try to seek out and save your Jewish girlfriend (or ex)?
Battle of Berlin is without humanity. Will you share your non existent rations with starving children on the streets? (Your health bar goes down if you don't eat) You get mission orders to forcefully enlist old men and children, and to hang or shoot random people and families. After Germany surrenders, you can choose to break out through the Russian lines west of Berlin and try to surrender to the Americans; or you can surrender to the Russian. If you chosen to marry a German girl in part IV, then she is pregnant now, so will you use her? protect her? or leave her?
Part VII The Aftermaths. If you surrendered to the Russians, you can choose through your actions as to whether or not to lie about being an SS officer. If you are found to be SS, you are shot on the spot and the game ends. If you get by, then you are sent to a labour camp in serberia, (possibility of a sequel if you get released into East Germany in the early 50s). If you surrendered to the Americans, you plead you were just following orders, of course whether you were or were not, only you know for sure. You get off lightly in the post war chaos, then moves to Argentina. Then many years later, you are an old man with a wife, kid, and grandchildren, and collegues and friends, etc, working as a mechanic like a normal person. But the Isreali secret service finds you, and points a gun at you. How can you plead to the Holocaust survivors to not kill you?
I know if you read this you are probably thinking I would just choose to disobey most of my orders,and end the game by being executed as a traitor. But the style of the game would be to introduce the atrocities step by step, from "if you don't kill him, he will kill you." to "these actions are for the greater good" to "It's fun to torture people." And to introduce the idea of peer pressure and societal pressure. Also everything you've been taught at this point is Patriotism, Loyalty, Honour, and far as you are concerned your killings all justifiable, and whoever may die deserved it (much like the US counter-insurgence troops today). And to present SS officers as normal people, who would die for each other in battle, have loving families and friends, and act as gentlemen towards Germans; and of course also commits terrible atrocities.
One simple question for you: Would you allow this ^ game to ever reach the shelves if you were ESRB / MPAA / Wal Mart / (basically the person that bans games)?
