Terminus Firefight

Terminus Firefight is a cooperative gametype introduced in Halo Wars 2. In Terminus Firefight, players build both bases and armies to defend and survive against an onslaught of enemy forces. This new mode is included with the digital expansion Awakening the Nightmare, released on September 26, 2017.

Gameplay
Up to three players amass armies to defend both their bases, and their Forerunner terminus node against an ever-increasing and intensifying hoard of attacking enemies.

Players have to battle against UNSC, Banished, and voracious Flood forces while fighting for survival. With the ability to construct new defense measurements such as spike floors and barricades alongside classic Halo Wars gameplay features like base-building, tech trees, and Leader power usage, this modes adds an entirely new tower defense-style twist to the classic wave-based Firefight mode.

Maps
This mode is only playable on the map The Last Bastion.
