Horizon

Mass Effect 2 (Legendary Edition) guide · First Collector attack

Commander Shepard investigates the human colony Horizon, which has gone completely silent following an assault by the Collectors. The squad must fight through waves of Collector forces and Husks to reach the colony's defensive space cannon and drive off the Collector cruiser. After activating the defense grid and clearing the final landing pad, Shepard has a tense reunion with an old squadmate from the first game.

Enemies

Collector Trooper

Weak to Biotics (Warp), Fire (Incinerate)

Basic infantry that can be directly possessed by the Collector General to gain barriers and increased stats

Collector Assassin

Weak to Biotics (Warp), Fire (Incinerate)

Ranged infantry equipped with particle rifles that deals high sustained beam damage

Collector Guardian

Weak to Biotics (Warp)

An upgraded Collector infantry unit protected by a portable hexagonal energy shield

Husk

Weak to Fire (Incinerate), Area of Effect knockdown abilities

Fast-moving melee cybernetic zombies that swarm the squad in large groups

Scion

Weak to Heavy weapons, Warp

Tough long-range mutated creatures that fire shockwave blasts capable of knocking players out of cover

Praetorian

Weak to Heavy weapons, Warp, Incinerate

Flying heavy boss unit protected by heavy armor and regenerating barriers that executes an instant-kill ground slam

Tips

Take out Husks quickly with Area of Effect powers or knockbacks, as removing their armor makes them instantly susceptible to instant-kill gravity effects like Pull.
When fighting the Praetorian at the defense cannon, kite it continuously around the central platform structure to break its line of sight and avoid its beam attack.
Destroy regular Collectors before the Collector General possesses them, or focus fire on Harbinger immediately with heavy weapons to halt his aggressive advance.
