Instead of having randomized objectives around the map, Blitz Firefight puts you on a small map with three capture zones that you must defend against waves of A.I. In Halo Wars 2, the core concept remains the same, while the mechanics have drastically changed. The most notable introduction is Blitz Firefight, which is Halo Wars 2’s take on the popular co-operative mode available in Halo where players fight off waves of increasingly difficult enemies. Even though Halo Wars 2 is designed as one of the most accessible real-time strategy games available on the Xbox One and PC, a few of the new modes can prove quite challenging.
