Bohemia Interactive has just released the new Warlords Mode for Arma 3. This new large scale competitive multiplayer mode puts two teams (NATO and CSAT) against one another on a massive map divided into smaller NPC-controlled sectors.
This is a pretty big update. The only thing better about Bohemia Interactive adding a new multiplayer mode like this is the fact that ARMA III is only $39.99 right now.
This sector, objective based gameplay seems like it'll really help with one of the big issues I had with ARMA. I know it's supposed to be a simulator, but it always felt empty the little bit I've played it. This should help with that, a lot, by focusing on smaller sectors. The best part is that it'll still take advantage of the huge maps.
