As was mentioned earlier, consoles haven't seen many WWI releases. If you are serious about playing these types of games (though if you're collecting, perhaps part of the requirements is having something console-based), I'd definitely try looking for options on the PC. Verdun and Valiant Hearts are the only ones that immediately come to mind, though.
*EDIT: Sorry, Valiant Hearts isn't a shooter, but it is based in WWI I think.
