Forerunner Forts are Forerunner outposts guarded by large beam turrets, Sentinels, and in some cases, Super Sentinels. The base itself 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.
