.31.17. Javelin Missiles Launched

You'll find this mission, labeled 'Stop Missile Attack' on the Galaxy Map, in Sigurd's Cradle, orbiting the third planet in the Skepsis system. Make sure you've completed the 'MSV Strontium Mule' mission first, as that unlocks Sigurd's Cradle. Once you enter the ship, a five-minute timer starts a few seconds later – your main goal is to reach and disable the missile launch console. Don't worry too much about grabbing every item on your first run; you can come back for anything you miss after the mission is complete.

As soon as you're inside, expect Batarian enemies. You'll encounter three of them in the hallway to the south. Keep heading north, bypassing the first door you come to.

Be ready for an ambush right after you bypass that door! As soon as you regain control of Shepard, sprint for cover. The main room ahead will be swarming with at least six Batarians, including a Commander. Your objective is to push further down, bypassing the door located below your current position.

Enter the room below. Here, you'll face a single Batarian Commander. Focus your fire on him. Once he's down, loot the Wall Safe for 3750 credits. Then, approach and interact with the Kill Switch Console.

You'll be presented with a choice regarding the console. The game doesn't reveal the outcome of this decision within Mass Effect 2, but it might have implications for future installments. Choose the option that best fits your Shepard's character.
