Two hidden swords on Halo 2 map "Halo Delta"

[SmokiestGrunl]

On Halo Delta, get to the structure where you can't go any farther with the tank. As you enter into the area, go left up the ramp and then up the little ramp until you come to the large block butted up against the wall. This is where you jump up to get to the Envy Skull (consult for more detail). There is a secret entrance behind this large cube.

I found the easiest way to move it was with the tank, although grenades do the trick just as well. You can drive the tank up there with a little patience. Aim at the WALL to the left of the stone, The explosion with slowly move the stone out of the way. Once the path is clear, walk up the dark ramp and there will be two dead grunts and two swords. There is also a high ledge in the next room that you can grenade jump up to, and then frag grenade jump up one more level -- allowing you to skip the fight inside the structure.
