After you have acquired the four new crew members Garrus, Mordin, Grunt and Jack you will receive an emergency transmission from the Illusive Man. Head to the communications room and after a conversation and a quick story scene youwill find out where your next destination lies: the human outpost of Horizon.
After landing, move forward and around the corner and continue along the path here until you reach an open area. As you arrive a swarm of collectors will enter the area to attack you. The standard collector drones are fairly easy to take out, but you will also encounter guardians (barriers) and assassins here. Watch out for the assassin's as they will use the particle beam gun (a collector heavy weapon) from a distance, which can do a tonne of damage to Shepard and your crew if they remain exposed to it for long enough. When the area is clear of hostiles, check the middle of the area to find a box of power cells. Proceed to the far end and near the pathway to the next area you will find a hackable data pad.
Follow the dirt path around the next corner until you reach a settlement, drop down to the area below and take cover. In addition to a couple of drones, a guardian and an assassin, the squad will also be attacked by a small group of husks (zombified humans who will run up to you in an attempt to melee attack).Try to focus on the husks first before prioritising other targets as they can be quite irritating otherwise. Once the remainder of the enemies are dead or dying enter the building on the right side of the area for a data pad and investigate the dead collector in front of the picnic table at the back of the area for a new research project (Heavy skin weave).
From the dead collector, look to the left to find a small opening; enter this to find an examinable Husk corpse. Check it out for a short conversation with your crew. Continue around the corner and head into the building directly in front of you. Move to the windows on the left side of the building and use them as cover to eliminate the Collector Guardians and Drones in the area below and to the left of your current position. When they are all dead, turn around and loot the wall safe here (you can also return back the way you came and examine the building across the way for a med kit if required).
Head out the door opposite the entrance and turn left, climb the low wall here and make your way between the scattered crates on the platform until you reach the stairs located at the back, left corner of the area. Examine the colonist in stasis here and continue up to the top of the stairs, in the room here you will find a hackable computer. Return to the stasis colonist and move across the path here to the building in front (don't forget to pick up a new weapon- Collector Particle Beam from the pod in the centre of the road).
After traversing the building, leave via the portal on the other side and takecover behind the low wall in front of the exit. After a short intro scene, you will be attacked by a harbinger (a drone who is taken over by the collector general) they have a barrier and heavy armour so can be a little tough to take down. The harbinger will attack in concert with a guardian and once both have bitten the dust, a swarm of drones will fly in from the far end of the area. Exerminate these guys and when the area is clear, look to the opposite side ofthe street from the last building you came through to see another open building, head inside to pick up a computer.
Return to the scene of the previous fight and check the building that was behind the collectors for a box of power cells. Exit the back door, and continue up the hill nearby towards the locked door. Bypass the security on the door and enter for a small story scene. Afterwards, loot the room of a canister of refined platinum and a med kit, before heading out the next door.
Once outside again, turn to the right and take cover. A guardian and group of collector drones will attack and one will become a harbinger. At the same time, at the far side of the area, a group of husks will become active and advance on your position. In the same location is a collector assassin with a particle gun to look out for. Prioritise the elimination of the husks first, then the assassin and then the rest of the collectors in the immediate area. Once the casualties start mounting, you will also encounter your first scion which will move in slowly from the right side of the area - these are large, heavily armoured husks that can fire a weapon that generates a large warp effect similar to Jack's Shockwave ability, this attack will do a massive amount ofdamage so it is imperative that you stay in cover whilst fighting them. You can kill scions by using anything that is good against armour.
Once the area is secure, look behind the building on the left for some power cells, head through the next building and up the small set of stairs behind .Look to the right and examine the dead collector for research project (biotic damage). Continue until you reach a locked, bypassable door. Instead of opening it right away, turn to the left or right and make your way through either building here, up the stairs and into a second floor room. Check out the computer in here for some credits before returning to the locked door. Bypass the security to unlock it.
Upon entering the next room you will be attacked by a pair of scions and a large group of husks. Try to take out the husks before they get too close or they will swarm you. If you have to leave cover to take them out, make sure you do it out of the line of sight of the scions otherwise they will hit you with their shockwave. Once the husks have been dealt with, focus your team's fire on the scions. Once the scions have been defeated, you can go to the raised platform in the centre of the area and use the computer for a short conversation with the Normandy.
As soon as the scene ends, a group of collectors will fly in from the far right side of the area. There are 5-6 drones (one of which will become a harbinger), an assassin with a particle beam and a guardian. At some point, you will also be attacked by a small group of husks. Killing the lot of them will result in a small wave of enemy reinforcements consisting of a couple of drones and a guardian. When they are all dead return to the centre of the area and await the next wave.
The next group of enemies will appear from the right side of the room in the form of 5-6 husks and once they have been dealt with another group of collectors will enter the area close to the door you came in from. This contingent of enemies is made up of 3 guardians, an assassin or two and a group of drones (one will become the harbinger). Killing these guys will cause 5-6 additional troops to fly in intermittently from the same general direction. After these guys have been defeated, return to the centre.
A short scene will play introducing players to a new enemy - the Praetorian.These are floating metallic constructs that move slowly around the area. They will fire laser beams which pack a mean punch with precise accuracy, so it is important to stay in cover for the most part. When the praetorian gets close to a squad members position, they will do a 'ground pound' style attack causing a small shockwave which can do considerable damage and is able to destabilise characters and knock them out of cover. To defeat it, just keep distance between the praetorian and Shepard and sprint to the opposite end of the room when it gets close. After a few rounds from a power weapon and some armour dampening attacks, the praetorian will fall.
Watch the scene and the mission will be completed.
