An old Alliance espionage probe has turned up in the Voyager Cluster. These probes carried nuclear payloads, and if the Citadel discovers these nuclear booby-traps, it would greatly embarrass the Alliance. Your mission is to find, disable, and recover the probe.
Walkthrough EditAgebinium. Land on the surface, and make your way to the mine (labeled "Alliance Homing Beacon" on the map). When you reach the probe in the back of the mine you'll trigger a trap set by Elanos Haliat, the mastermind behind the Skyllian Blitz. If Shepard has the War Hero background, Haliat will claim that he is having his revenge for Shepard's responsibility in repelling the Blitz (and Haliat's subsequent loss of reputation among his band of pirates when the attack failed), and sets the nuclear device on the probe to overload in order to kill Shepard. With either of the other two backgrounds, Haliat will still set off the bomb as a form of general revenge against the Alliance and because his operation had been discovered. You now have ten seconds before the bomb goes off to disable it.
Disabling the bomb entails disarming three hard points on the probe, each involving a mini-game or omni-gel, at 100 units each. These mini-games have a much longer sequence than most others, and thankfully progress more slowly. Once you've disabled the bomb, you'll discover that the way you came in is now blocked by fallen debris. The other airlock door, which was previously inaccessible, is now interactive and can be opened. Make sure to grab the upgrade kit right inside the door before you escape the mine and return to the surface. Your antagonist is just over the next rise with your Mako and some assorted criminals. Take out Haliat and his goons to end the assignment.sniper rifle, it is easier to snipe them one by one from above. Otherwise, run down the slope and quickly get in the Mako. Use it to clear the area and end the assignment.
Alternatively, take a roundabout way to the Mako, approaching at an angle where the Mako is between you and most of the camp. Sprint to the Mako as soon as you're able to, and you can get in the Mako and attack Haliat's gang with relative impunity with the Mako's mounted weapons.
Another way to get the Mako is to teleport back to the Normandy and then you can go back with the Mako and finish off Haliat's gang.
