How to Obtain Why Am I Here? Achievement
For this achievement you will want to load up the map Beaver Creek on Halo 2: Classic.
You will want to start by going up the ledge where the sniper is located.
From there you will see a few boulders on the ledge, jump up there.
Use a grenade to move the boulders, and you will see a note in the rock saying “Why Am I Here? – Not Sid”.
