HI BEN
From Halopedia, the Halo wiki
On the Halo 2 campaign level "Regret", there is an easter egg with the words "HI BEN" written on the ceiling of a hidden room that is dedicated to Benjamin Burnley of Breaking Benjamin, who wrote the song Blow Me Away that appears in Halo 2. There is also, in purple, the "rock on" hand sign on the right hand corner.

- A Sniper Rifle or Beam Rifle

Grenade jump there and go to the room to your right. Activate your Flashlight and go to a left corner and zoom in with your scope and you will see the message.'
Or
Continue the game until you reach the platform where the hunters are dropped and walk to the side of the platform facing the temple with the broken bridge. throw a grenade at your feet and jump and you should be launched across in through the window on the other side then simply follow instructions from the first method above.
