So I was searching the internet and I found this site where you can download roms for Java mobile devices and there are a bunch of CoD games on Java (CoD 2,3,MW,WaW,BO1) And I found this title called "Call of Duty 2: Stalingrad" and I know most if not all CoD games, but I never hear of this one, I tried searching about it more on the internet but all a found is roms of it and on YouTube there is literally just 2 video of it, the game seems to be 3D fps, that's all I have to say
