34.03. Collector Station: Valves

When you enter the Collector Station, you'll need to select a tech specialist to go through the vents. Since there are no synthetic enemies in the base, sending your best engineers won't impact your team. However, make sure to pick a decent Fire Team Leader, as that will ensure the safety of you and your Vent specialist.

• Vent specialist options: Legion, Tali

Fire Team Leader options: Jacob, Miranda, Garrus

Fight through the enemies, killing them as quickly as possible to activate the valves. In the first area, there will be about six drones along the northeast side, which you can destroy quickly as you proceed. Release the valve and move on. Note that you don't have to kill all the enemies before releasing the valves.

As you head down the path, groups of three drones (with one morphing into Harbinger) will block your way. Release the second and third valves, using cover when necessary.

There are no enemies on the way to the fourth valve, and you can sprint often to try to keep your specialist's health high.

For the fifth valve, there will be a large number of drones blocking your path. If your specialist reaches half health, it's recommended to go for the valve and take care of the remaining Collectors afterwards.

There are no enemies on the way to the sixth valve. However, as you turn the corner, you'll face three drones, so be patient and don't rush ahead here.

After the three drones, there will be an Assassin to the east, and the seventh valve to the north. Kill the Assassin, then get into cover and regenerate some health. You don't have to kill the remaining enemies, and can instead go straight for the final valve. If you've done everything right, everyone will be alright.
