Trebin Overview

Trebin is located in the Antaeus system of the Hades Gamma cluster. You’ll be able to complete the “UNC: Missing Survey Team” assignment during your stay here.

1 – Arrival

Trebin’s climate is actually fairly pleasant, so don’t worry about stepping out of the Mako during your time here.

2 – Plutonium Deposit

Survey this Plutonium deposit to get one step closer to finishing the “Rare Earths” section of the “UNC: Valuable Minerals” assignment and to earn a reasonable amount of experience and credits.

3 – Crashed Probe

This space probe is being investigated by a group of five Scavengers, so you’ll have to shred them with the Mako’s cannon or machine gun before you can loot the probe’s upgrades for yourself.

4 – Transmitter Tower

Upon closer inspection, you’ll discover that this tower is “tranmitting tightbeam signals into geosynchronous orbit”, which disrupts the local survey team’s GPS satellites and causes them to crash to the planet’s surface. Hmm.

5 – Research Base

Loot the medical kit and storage locker in this deserted research base, then check the computer console to learn that the survey team unearthed some sort of alien technology. Perhaps you should explore the excavation site to the north?

6 – Excavation Site

The mining tunnels below this dig site are crawling with Husks, so be prepared for battle once inside. When you’ve killed them all, you’ll discover that the Husks were all that’s left of the ExoGeni survey team. Apparently the team was converted into the cybernetic beings by devices similar to those used by the Geth on Eden Prime. This discovery completes the “UNC: Missing Survey Team” assignment.

Before leaving, take a moment to search the tunnels for five lootable containers: a crate, two locked crates, a sludge canister, and a secure crate.

7 – Uranium Deposit

Survey this Uranium deposit to get one step closer to finishing the “Rare Earths” section of the “UNC: Valuable Minerals” assignment and to earn a reasonable amount of experience and credits.

8 – Thresher Maw and Ancient Debris

After you’ve dealt with yet another Thresher Maw, you can recover “a small tattered flag” from the debris lying naerby. The flag is marked with the Nimines Colony insignia, which puts you one step closer to finishing the “UNC: Turian Insignias” assignment.
