With development on Battlefield 1's updates slowing down, the time has come for free stuff. DICE is giving away the first expansion, They Shall Not Pass, for two weeks. The offer is currently up for Origin and Xbox One players, but at the time of writing, it's not ready for PlayStation 4 users in North America.
They Shall Not Pass is the one with the French army, Frontlines mode, the Battle of Verdun, the Trench Raider class, and the mighty Char 2C tank, among other content additions. Pretty sweet deal.
