Shield Barrier

The Shield Barrier is a fortification employed by the Banished. The Shield Barrier bears a visual resemblance to the Covenant Energy wall and Anti-vehicle barriers, blocking all units from passing through. The Shield Barrier can be constructed in the campaign of Halo Wars 2: Awakening the Nightmare and in Terminus Firefight for 200 supply and 200 power. The barrier requires Tech Level 2 to construct, but is offset by having all Banished players in Terminus Firefight start with a Shield Barrier already constructed at the start of the game for free.

Upgrades
