- This will cause a number of Vex: Goblins and a Minotaur.
- Go into the next room and you will be fighting yet more Vex.
- It is much the same mix of Goblins, Hobgoblins,and Minotaurs that you need to fight through.
- You need to clear these rooms of Vex.
- Just inside this second room, go over to the left, toward the windows overlooking the drilling site just outside.
- You will find a control console you can interact with.
- Do so to trigger the next part of the objective.
- Turn to the right of the control console you just used.
- Go through the first door there and down the hallway there.
- This will bring you out to the drill site itself in Giant's Scar.
- Go straight across the drill site to the open doorway across from you.
- Through the door, head down the hallway there.
- Go past the remaining construction materials and through to the doorway ahead.
- Continue on the down slope through the hallway.
- This will lead the Guardian down into Excavation Site II.
- The first room you arrive in will have a number of Taken in it.
- You can either fight the Taken Centurions, and Taken Goblins, or just run straight through the door in the back of the room.
- At the top of the ramp there, you will find a Taken Phalanx.
- Defeat them and head up the ramp to the left and into the next room.
- This room will have you fighting another Taken Centurion, Taken Phalanx, and Taken Goblins.
- Having cleared the room or have a chance to run through.
- Go on up the ramp and get up to the next room.
- In this room, you will need to deal with a Taken Minotaur.
- This will lead to a second wave of Taken spawning in.
- This round you will be fighting a Taken Phalanx, Taken Goblin and another Taken Minotaur.
- The third wave is very similar to the second, with 2 Minotaurs coming in after a few of the other Taken have been defeated.
- Focus your fire on the Taken Goblins first to ensure they cannot render the Minotaurs invulnerable.
- Clear the remaining Taken after that to remove the barrier blocking your way forward.
- In this room, go through the door in the back right.
- Just in front of you are the next set of controls you need.

- Head out of the shaft and over to the left.
- Look to the right in the next room, there are more Taken for you to deal with.
- This will place you against a Taken Wizard who you will need to beat.
- Go through the door that it was guarding into the next room.
- A Taken Phalanx waits on the other side.
- In this large room, you will see Taken and Vex fighting.
- You can either just run through or fight through both sides.
- You want to head through the door in the back right of the room.
- Head back up the ramp and back to the drill site.
