In the multiplayer map Beaver Creek there are two high up ledges with sniper rifles, the one to go to is the one next to blue base. Once there you will see that slightly to the right of where the sniper rifle is pointing there is another cliff. Jump on that cliff, then on that cliff you will see a large bump with two rocks on it. Knock both rocks off by melee attacking them several times. Behind the largest rock there is what looks like hand-written text that says "Why am I Here", there is some smaller text underneath "Why Am I Here" but I cannot read it. Make sure not to get too close to the words or zoom in on them otherwise they can not be deciphered.
