Ok this has been bugging me for a very long time now, ive done all the quests for the Boomers (everything)
but i still cant figure out how to get the codes to use the WW2 simulator, i thought if i was good enough eventually someone would just run up to me and give me the codes but i was wrong,
Does anybody know how to get the codes or if its even possible to use the WW2 simulator thanks...

As far as I know, you can't use the flight sims at all. They're considered sacred by the Boomers, so no outsiders can ever use them, even if you save them fifty million times and they're forever grateful.

Thats a little bit of a shame but thanks, i know theres a train-station nearby (if you follow the train tracks out of the bloomers base)
But i need a lockpick skill of 100 and mines only 50, maybe just maybe.... there might be something in there :shrug:

From a technical standpoint, the scripting of the sims provides no way for the player to use them.

You can't get access to the flight simulators (Aren't they against Chinese craft? That would suggest they don't simulate WWII ). Even if you could mod access no flight simulation was ever developed and included in the game.

The train tunnel is an alternate route to get to the boomers which lets you bypass the firing range.

I've got a feeling we'll never be able to use them. I don't even suspect there will be DLC to accommodate said usage.
