Walkthrough

1
After completing all recruit missions and speaking with the Illusive Man, you will be sent to Horizon to investigate.
2
You will encounter your first Collectors. Drones can be possessed by Harbinger, granting them Shields and Armor. Killing Harbinger causes him to possess another Drone. A strategy is to eliminate as many Drones as possible before focusing on Harbinger, or to attack Harbinger during his possession animation.
3
You will face several Collectors. They use a harmful particle beam. The colony provides ample cover; use it to your advantage against groups of 4-5 Collectors.
4
The map is linear, with items often hidden inside residence units. Horizon is a large colony, requiring significant walking. Continue clearing areas of Collectors and moving forward. Collectors typically fly in from above.
5
You will encounter frozen colonists and more items before the next fight. Pick up the Collector Particle Beam, a decent laser weapon with more ammo, great accuracy, no recoil, and no need for reloading. It's recommended to keep it equipped until Heavy Weapon upgrades are acquired.
6
Further ahead, you will encounter the Collector General, Harbinger. Collector pods can be used for cover, but Harbinger's missile-seeking weapon can dislodge you if it hits nearby.
7
After clearing the area, check residences for items and bypass the door to proceed.
8
Beyond the door, you will find an unfrozen human survivor. Talking to him provides a new objective: fix the defense tower targeting systems.
