Ignore all the other games that put this in. They're making up details and facts based on wishful thinking that was never realized. It was built to fulfill a requirement that a plane would fly 1000 km/h but it never did. It also only had 2 mockups, and they were not even preproduction models but more like testbeds to confirm the design could fly... which technically it could but it was highly unstable and this was before any fly-by-wire computer controls like our B-2 bomber has to keep it perfectly stable. Those didn't even have retracting landing gear and it was never armed.
Pipe dreams and propaganda. Even if they had got it to a point that it might have tried some form of combat, it would have been very slow, very unmaneuverable (spin prone and hard to get out) and the engines weren't producing as much power as hoped and were more than likely to fail than to perform as expected. Remember that Germany didn't have access to certain metals that could withstand the forces/pressures/heats of a turbojet engine, so they made most of theirs out of lesser metals which failed after very short lifespans.
This is a much-hyped "never-was" of a plane.
EDIT: P.S. That whole "Stealth to radar" utter nonsense was put forth in the 1980s and was not part of the original specs or intent in 1945. An interesting article of the study that came out of that hype can be found here, where they analyzed the comments from the 1980s and (IMO) but them to rest permanently:
