Developer: Black Matter
Release Date: Q2 2018
Another large-scale WWII simulator, Hell Let Loose is aiming for a realistic style. It's mechanics focus on teamwork (along the lines of Squad) as you set up forward bases and weapon nests across the battlefield.
Yes, it will be massive -- as these games need to be -- with up to 100 players battling each other at once. There's also a painstaking level of work going into the game's maps, with the developer recreating 1945 French villages based on archived footage and satellite photos. So needless to say, this game is going to be accurate.
