Just prior to the announcement of this fall's expansion of Halo Wars 2, Awakening the Nightmare, we had a chat with executive producer Barry Feathers who talked to us about of the components found in said expansions, the Terminus Firefight.
"It's more of a traditional base defense firefight. You build bases, you can use all the leaders that we've had in all the DLC that we've released up until this point. Different strategies. We're adding barricades which is a new defensive structure and it's just about how long can you survive. How long can you last? What new techniques are you employing to last just that little bit longer?"
Awakening the Nightmare will also include new story campaign mission where the Banished take on the Flood, as well as new cinematics. There will also be new multiplayer maps (available to all players), as well as new leaders.
