Infiltration

Start Area Normandy SR-2
Mission Trigger Go through Omega 4 Relay
Before you start this Mission, you should have the loyalty of every crew member, and all three otherwise useless Normandy Upgrades. This will help prevent anyone from dying. If you want to save the entire crew, you need to hit the Omega 4 Relay immediately after the IFF becomes available. Any delay and you will lose people.

Entering the Omega 4 Relay triggers a long cutscene interrupted by a few fights. Your first task will be to form a team to take down an Oculus in the Normandy's cargo bay. You'll be able to choose a squad for this battle, which will happen in two parts.

Once you've landed, you'll need to choose a tech specialist (preferably Tali, Legion, or Kasumi) and a secondary team leader (preferably Garrus, Miranda, or Jacob). Any other choice will result in someone dying. You're going to be fighting collectors here, which means lots of barriers and no shields. Warp is very useful. You'll have to hit a series of 8 heat exchanger gates before time expires. Note that battle immediately ends when you hit the last one, even if there are Enemies alive.

The Mission ends at this point, leading into The Long Walk. Your Heavy Weapon Ammo and medi-gel is automatically restored.
