Sniper Elite 4 – How to Get Greta and Eternal Struggle

I just did that Hilter mission again less than 12 hours ago.

Tips to Get Greta and Eternal Struggle

The Eternal Struggle is obviously in the armory as you know. To get the key to the Armory you go to the very top platform and drop down to get into a window. There’s an ally locked in a room there that is dying, and when you approach him there’s a cutscene and you get the key from him before he dies.

That platform location: if you are entering the sub-pen inside area – let’s say entering from the front end (south) next to the sniper you just killed, you look to the right side and there’s a top platform there with a low wall all around it, above one of the locations where you have to disable the control panel. Crawl across the pipes and go to the north end of that platform and drop down to the window to get inside that room (the door to the room is locked). Kill the inside area sniper before you drop down to the window, so he doesn’t shoot you as you try to drop in.

If you are entering the inside area from the caverns, and going up through the ductwork, you already wind up on that top platform. Easier that way.

Hope that helps.
