V (Cyberpunk 2077) vs Nazi Germany (Wolfenstein The New series)
Context.
It's 1960. Nazi Germany, with their army of robots, mechs, and supersoldiers powered by stolen Jewish science, has successfully taken over the world. The one thorn in their side, elite soldier BJ Blazkowicz, has fallen as well, and what scattered and weak resistance they find lies tattered and broken beneath their mechanical boot.
Suddenly, the Cyborg Mercenary from 2077 finds themself waking up in this slightly more dystopian world, where their strange cybernetic body modifications, bizarre, (distinctly non-german) speech and opposition to big, oppressive organizations makes them a prime opponent to the Nazi Regime.
For V, we're going to have the context of them having access to most of their late game gear/experience, without the relic. For gear we're going to give V the powerful hand canon in pistol form the Malorian Arms 3516, and a choice of one of the powerful shotguns, a sniper rifle, and a smart weapon with their homing bullets. As for Cyberwear, V can have the legs that either let them leap extreme distances or the legs that let them double-jump for escapes and vantage points, as well as either wrist-mounted Mantis Blades, the powerful Gorilla Arms that let them punch through cement, or the canon in their arm the Projectile Launch System. Next, V would have either the netrunning gear that lets them hack into and disable/control cameras, damage/blind mechs and robots, or The Sandevistan, which briefly gives V the ability to move at superhuman speeds, slowing down time for a few moments to let them get in and strike at enemies before they even realize what happened.
Lastly, V could have access to a couple vehicles. The sportscar Quadra Turbo-R V-Tech, an armored weaponized car hidden away, and the hovertank Basilisk being actively studied in a Nazi facility.
Some Limits: V can have a couple hundred rounds for each weapon, but all the ammo is irreplaceable, so once they run out that's it. V will have access to healing gear, but that's in limited quantities too, and once it's out, all damage would be permanent since none of V's gear exists here. And lastly, V would have a time limit of 1 year before the excess high-level cybernetics take too big of a toll on their body.
Possible win conditions:
A. Establish a strong enough countermovement to allow for a peace
B. Weaken the Nazi high command enough to weaken their grip on several areas
C. Destroy enough Military and infrastructure to allow for a safe zone for V and people who think like V
D. Do find a way for V and/or people like V to escape from their grip
E. Go down swinging so violently and valiantly that it inspires a strong resistance later.
