From Halopedia, the Halo wiki
Template:Ratings Forerunner Forts in Halo Wars are outposts guarded by large beam turrets and Sentinels. It also is surrounded by shield walls with ends meeting at the turrets. They are capable of retracting in on itself after sustaining enough damage. Twenty seconds after the fort retracts, it is available as a base location.
