Bohemia is still working on Arma 3's final campaign DLC episode, but it's also looking at fresher, more exciting additions. The developer today announced a free DLC named Zeus, which will turn one player into a 'Game Master' to run an Arma 3 session a bit like a Dungeons & Dragons DM. They'll get to set and change objectives, spawn units, and mess with the world, all in real-time.
