UNC: Lost Module

When you arrive in the Attican Beta Cluster, you'll receive a message asking you to travel to the Hercules system there to find a data module that's crashed on the planet. Land on Eletania when you reach the system and make your way to the module.

You'll discover that a monkey from one of the monkey tribes nearby has apparently stolen the data disc. Head to the northernmost monkey colony on your map to find a set of caves; one of the monkeys in the rear room will have the data disc. Grab it from him and fight your way through the Geth to finish the mission.

UNC: Hostage

Another quest you'll probably pick up by riding an elevator in the Citadel. This one explains that a politician has been kidnapped by biotics, who are on a freighter in the Hades Gamma cluster, Faranita System.

Hostages rarely make it out alive.

Head there and board the MSV Ontario. You only have three minutes to kill all of the biotics in the first large room here; any longer, and they'll kill the hostage. It shouldn't be too hard to take them all down in that timeframe, though. When you do, you'll have to enter negotiations with their leader. If you don't have the proper Charm/Intimidate skills, the hostage will probably die; otherwise, you can convince the remaining biotics to surrender.

UNC: Asari Diplomacy

In your travels, you'll eventually find a datapad from a mercenary named Dahlia Dantius, who was threatening her diplomat sister on the Citadel. There's probably a starter quest for this, but we happened to run into Dahlia on an otherwise unremarkable planet and killed her. If you return to Nassana, in the embassy bar on the Citadel, you can try to sweettalk her into letting you buy prototype Asari weapon mods.

UNC: Rogue VI

You'll obtain this mission after warping into a system; you'll receive a communication from Admiral Hackett telling you to return to Sol and help defeat a training VI that's gone rogue.

Head to the Local Cluster and find the tiny dot near Earth that indicates Luna's presence. Land on it, find the facility, then use one of the entrance consoles on the structures outside after defeating the turrets. Inside, you'll find a swarm of assault bots, as well as eight VI conduits. Destroy the conduits, then repeat the process at each of the other facilities to finish the VI off entirely. (The binary text you get at the end of the mission simply reads "HELP".)

You'll be able to select a specialization for your class at the end of this mission, for some reason. This will be different for each character class, so read your options carefully! The choice that you make will be added to your skill tree on top of the default character class skill. E.g. our engineer selected to be an Operative, so the Engineer skill had five or six ranks added to the end of it with added bonuses for the electronics and decryption skills.

A lot of the quests are found like this, with you hacking into enemy terminals.

UNC: Beseiged Base

After warping to a system (for us, it was the Gagarin system in the Armstrong Nebula), you'll receive a transmission about a beseiged research facility in the Cacus System of the Hades Gamma cluster. You'll have to find some way to eliminate the biotic terrorists while saving the researchers.

Head to Chohe, in the Cacus System of the Gamma Hades Cluster. You need to kill the biotics here without harming the scientists. The scientists will wander around the combat area, getting in your line of fire, so you have to be careful. The best way to proceed here will be to enter the combat zone and try to lure the biotics back through the hallway towards the entrance. When the bulk of them are cleared out, you can make your way through the rest of the facility, trying to avoid getting anywhere near the scientists; that'll help you avoid hurting them by accident. When all of the biotics are down, return to the Normandy and use the map to relay the info to Admiral Hackett.

UNC: Distress Call

If you head to the Hydra System of the Argos Rho Cluster and attempt to investigate the planet Metgos, you'll receive a distress call from a ship that's crash-landed there. Land on the planet, find the wreckage, defeat the Geth ambush, and move on.

UNC: Lost Freighter

We never actually got the starter quest for this assignment, but we stumbled across a freighter in the Ming system of the Gemini Sigma cluster. After boarding the ship, you can play the logs of the crew to discover that a biotic named Julia went crazy after her boyfriend was about to be taken off life support. She's killed the crew, but she won't be able to do much to you. Kill her, then make the call as to whether or not you want to take Jacob off life support.

UNC: Espionage Probe

If you enter the Voyager Cluster and head to the Amazon system, you'll receive this quest. Apparently a booby-trapped probe has landed somewhere in the Voyager Cluster. You need to find it and dismantle it before anyone else does.

You can head down this hill and hop into the Mako to finish off your foes relatively easily.

Head to the Amazon system and land on Agebinium. The probe is located in a set of caves. Unfortunately, when you get there, it's apparent that the caves are a trap! For you! Personally!

The nuke will have three hardpoints on it that need to be disabled. The minigames here are easier than they normally are, but if you have the omni-gel it's probably easier to simply spend it to disable them. When you do that, take the back exit to come out on top of a hill above your enemy's position. You can charge down the hill to the Mako there and use it to clear out your foes, then return to the Normandy.
