How to Start Making an Impression Side Quest

You can only start this side quest after you’ve managed to settle Eos. SAM will tell you that there has been some strange seismic activity on the planet. Go and talk to Hainly Abrams, and she’ll tell you what needs to be done. Accept the quest and you’ll get an automatic navpoint to the place you need to put the first seismic hammer. The site is crawling with Kett, so be on your guard.

Place the first seismic hammer and check your map for the second location. However, when you arrive there, things get a little complicated. In Sawtooth Ridge, you’ll run into a scout of Advent, a small colony that acts independently of the Nexus. He seems friendly enough, however, and he’s willing to propose a deal.

Making an Impression Choice – Tap for Water or Natural Gas

The scout explains that Advent needs the water supply for themselves. Instead, he proposes that you use the seismic hammer to tap into a reserve of natural gas. The Advent will then mine it and trade with the Nexus. The seismic hammer places are close to each other. The one nearer to the scout’s position is for water (1), the one further away is for the gas (2).

Which one you choose doesn’t seem to affect the game in any meaningful way, so it’s up to you. Whichever you choose, be prepared to fend off Remnants once you place the hammer.

Follow the navpoint to the third and final location. Place the third seismic hammer, and be prepared to fight the Eos Architect boss.

The battle against the Architect has several phases. The fight is long, but not too complicated. Just arm yourself with patience and your best damage-dealing build.

When the fight starts, the first step is to shoot at the glowing parts of the machine’s legs. You have around half a minute to damage one leg over 50%, or else it will close up and release a wave of Nullifiers and Breachers. Make sure you order your squad members to focus their fire onto the exposed conduits. Consumables such as Incendiary Ammo are of great help, if you have them.


After you’ve damaged one of the leg conduits enough, the second phase will begin. The Architect will open it’s head conduit, which is basically the glowing red center inside its mouth. This is the stage when you’ll start dealing real damage to the robot. Focus all of your fire on the conduit and give it everything you’ve got.

Once you damage the Architect enough, it will try to run away. Get into the Nomad and follow it to the next location, which will likely be another seismic hammer. Begin the cycle again. Keep in mind that you can only hit the head conduit when it’s glowing red. You might come across a phase where the Architect will be holding you under heavy fire, but the conduit won’t glow. If that happens, just find good cover and wait until you can deal damage again.

Eventually, you’ll destroy the head conduit and the Architect will fall. However, it’s not over yet. Run over to its head and interface with it. This will send it flying into orbit, and the battle is over. You can later scan it from orbit.
