343 Industries has teased the next piece of DLC for Halo Wars 2 on Halo Waypoint (via GameSpot)
‘We’ve got some pretty awesome new details about the game’s next DLC leader that should be emerging next week, so grab a buddy and be ready!’ 343 Industries said in the blog post.
The first bit of extra content came in March, and the studio has stated that new leaders will be added on a monthly basis via DLC, so the timing checks out. Each leader can be purchased separately, or as a package thanks to the season pass.
