The Sequence

Enter the Command Spire: Upon arrival via Pelican, clear out the initial Brutes, Jackals, and Grunts. Be prepared for Elite Brutes; aim for their heads. Use AI Scan to find the terminal, interact with it to trigger a cutscene. The mission objective shifts to collecting data from four beacons. After leaving the Command Spire, you'll be attacked by two Banshees. Use the nearby Skewer weapon to destroy them in one hit.

East Beacon: Travel northeast using the Grappleshot to reach the East Beacon. You'll encounter an Elite Brute with white armor, which uses ranged attacks, melee, Energy Sword, and Active Camo. Use the Threat Sensor to counter its stealth and a Skewer for an instant kill, or any weapon if the Skewer is unavailable. Near the bridge to the beacon, face Elite Brutes with Ravagers or Hydras, and smaller flying enemies that fire energy blasts. Aim for the eye cores of the flying enemies. You may be ambushed by two melee-specialist Elite Brutes; use Dynamo Grenades to stun them or find high ground. To the right after crossing the bridge, you can find a non-mission collectible Spartan Core. Closer to the beacon, destroy a plasma cannon (an M41 SPNKR Rocket Launcher is nearby) and defeat remaining Brutes, Jackals, and Grunts. A Brute Officer guards the beacon; aim for the head. Interact with the terminal to enter the beacon, find a Banished audio log, and collect the necessary data.

South Beacon: Ideally, fast travel to the South Beacon using a nearby FOB. If not, travel through the landscape, clearing enemies. Capture FOBS along the way for future fast travel. The South Beacon area is heavily guarded. You must destroy two Wraith tanks protecting the beacon, along with other enemy types. Approach from behind to find a Spartan Core. On the second level, you can acquire a Ravager from an Elite Brute.
