How do I beat the Reaper on Rannoch?

I’m having trouble with the last of the Rannoch missions, where Shep wakes up and takes on a Reaper.

Shepard has a targeting laser which will call in an orbital strike with the combined might of the Quarian Migrant Fleet, but there’s two major problems standing between the commander and victory.

  1. The Targeting Laser takes a while to power up.

  2. The Reaper is trying to kill you.

I can consistently avoid the Reaper’s attacks for the first volley, but each time you hit it, the Reaper moves forwards, giving you less time to dodge future assaults. Is there some key to avoiding the Reaper’s attacks? Strafing doesn’t seem to be enough.


This was a very frustrating battle. The trick about the targeting laser is that it doesn’t actually require you to complete the targeting lock in a single fire. You can completely let go of the trigger and run to the side, then re-aim, making increments of progress each time.

The other thing I noticed, which was non-obvious to me the first several times I died in the final slow motion sequence, was that the targeting seemed to work much more quickly if your aim was as close as possible to the center of the red eye (not just “Am I in the blue target circle?”). I haven’t replayed to confirm with Science™ that this is indeed true, but on my successful completion I made sure to aim dead center and it was all over very quickly.
