How do I beat the Reaper on Rannoch?

Solution 1:

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.

Solution 2:

This boss fight is pretty tough, there are a couple of things that you can do to help get past it.

Immediately lock on and hold FIRE to hit it once with an orbital strike.

The tough part of fight is that you MUST stop to focus the orbital strike beacon, but you have to move often to avoid the Reaper’s laser.

Note that you can roll to avoid the laser mid-focus and pick up focusing the orbital strike afterwards. However, it will become very difficult to just roll out of the way at the last second. Rolling won't affect your focus as much as running, but by the 3rd strike, it is easier to avoid death by the Reaper laser by turning and dashing/running from side to side.

This video walkthru shows the rolling technique very clearly.

The fourth strike is the toughest of all, and you will need to focus in small bursts. After making this strike, you will enter a slow-motion scene to engage your final shot. Just point, focus and blast away.

Easy, I was looking up how to beat him, but easily enough, to beat the laser, just strafe. Now Let me explain... as the reaper is powering up his laser, he will shoot his laser in the direction you are CURRENTLY moving. The direction you are moving JUST AS THE LASER STARTS TO SHOOT is the direction the laser will keep moving. So immediately when he starts to shoot his laser, move in the opposite direction. I can easily just continue strafing and locking on by using this tactic without stopping, or having to roll or anything. If you keep moving in the same direction as he starts to shoot the laser, you are bound to get hit, or you have to roll, which you still have a chance to get hit...

As to locking on... I couldn't figure out why i kept getting to slow mo laser and couldn't dodge it... apparently you have to hit him right in the red lol... :D Hope that helps
