Take a look at the Sniper Elite series. It’s third-person and plays a lot slower than a COD game, but it is full co-op and takes place in WW2. The newer entries also look pretty nice.
Really excited for this and the Broken Sword Remaster that comes out on the same day. Shadowgate was my gateway to learning English. I sat in front of my NES with a dictionary when I was like 10 or 11 years old. Even managed to beat the game that way.
