Rendezvous with the Pilot (2)
| 1 | Once you get out in the open, pick up some fusion coils near the edge of the hill to help you take out the enemies below. Restock on ammo if you need to as well. |
|---|---|
| 2 | You can try to shoot some of the fusion coils on the lower area when any of the enemies come near them. |
| 3 | Other enemies will be positioned on high ground near the cliff wall and will try to pepper you with shots from afar. Take them out before going down to the lower area of the outpost. |
| 4 | When you are ready, head down to the lower area and mop up any remaining Grunts, Brutes, and Jackals hiding behind cover. Use any grenades you have saved up or hurl fusion coils found nearby when groups of enemies comes at you. |

| 6 | Once the Elite Major is alone, feel free to engage him up close if you want. Grenades or head shots can make quick work of the Major but be sure to stay on the move when you are toe-to-toe with him. |
