Foundations

Locate the Weapon

1	Proceed ahead and take out the enemy ahead. Then, grappleshot across the gap. Follow the path to the left and kill off the Grunts and shielded Jackals in the area.
2	A ship nearby will deploy some Brutes to the fray. Fight your way toward the marked location to the north.
3	Go through the marked door and follow the corridor to another large room.
4	Move along the beams of light toward the destination. As you move to the passage on the left side, Grunts and Jackals will appear so take them out. Use the fusion coils to clear them out quickly if they bunch up.
5	Further in the level is a device radiating blue energy called a gravity lift that lets you go up to the next area. Afterwards, go through the door and follow the corridor to another large room. Turn right and move along the platforms while jumping over the gaps.
6	After crossing the light bridge, go through the door. Go up the ramp and through another larger door that leads to a wide room with Jackals and Grunts scattered around the area. Take them out while moving from cover to cover to avoid taking too much damage.
7	Once the enemies have been dealt with, go through the large door on the opposite end.
8	Move past the large room with the pillars showing what seem to be shapes of the human body etched on them. Approach the Weapon on the pedestal.
9	Watch the cutscene.
10	After inserting the chip, the platform will begin to move up. Once the platform stops, get off and go up the ramp on your right.
11	Go through the door ahead and follow the corridor. When you reach the hallway with the window in front of you, go left.
12	The Cowbell Skull can be found nearby. After passing through the hallway, grappleshot up the top of the pillar closest to you on on your right. From where you land on, you should be able to scan the location of the next skull above (it is on a ledge way up the area). Look up to your left to see a part of the ledge sticking out that you can grapple up to, allowing you to grab the Cowbell Skull.
13	You will eventually reach an area where you will need a Power Seed to power the light bridge. Head down the ramp and grab the Power Seed on the wall. Plant it on the terminal and cross the bridge.
14	Watch the cutscene when you reach the pedestal.
15	Cross the light bridge ahead and go through the door. Continue following the mission marker to reach another pedestal.
16	Move along the platforms that come up in the middle of the area. Take out the Grunts and Jackals. Further along the path are some Brutes as well.
17	Interact with the next pedestal.
18	The platform that comes up ahead will have Grunts who will ambush you. Take them out while avoiding fire from more enemies above you. You can try to pick them off by using the walls on the side as cover.
19	After clearing out the enemies, grappleshot up the platform or go up using the ramps on the side.
20	More enemies will appear so clear them out.
21	Go through the door and move through the hallways until you reach a room with a terminal in the middle.
22	Grappleshot to the upper ledge and grab the power seed. Then, use it to power the terminal which activates the gravity lift.
23	Use the lift to go up.
24	Go through the door and race across the hallways. Examine the device near the dead Spartan to get the Mjolnir Suit Upgrade.

Reach the Surface

1	Go up the ramp and go through the door. Take out the Grunt ahead.
2	You will eventually come to a large room where several enemies will be patrolling. Pick them off by moving along the sides and sniping them or use the fusion coils found all around the area to clear them out.
3	After taking care of the enemies, head for the marked location and go through the passage. Move through the corridor.

Restore Power to the Generator

1	Cross the long bridge and grab the power seed ahead.
2	Head back to the large room and plant the power seed on the terminal to power the generator.

Deploy the Weapon to the Terminal

1	Head to the terminal on further ahead on your left and interact with it.
2	Watch the cutscene. Afterwards, prepare to battle Tremonius.

Defeat Tremonius

1	Tremonius will be accompanied by several Jackals. You can take out the minions quickly by luring them near fusion coils. Afterwards, focus on Tremonius.
2	Your first priority is to destroy Tremonius’ shield using Plasma weapons. Once it is down, pepper him with any strong weapons you have on hand, especially Sticky Grenades. You can also grab the Disruptor by the weapon rack across the elevator to whittle away at the boss’ health.
3	Once Tremonius is defeated, use the elevator to reach the surface.
