I made it through most of Gravemind on the Halo 2 LASO (Legendary All Skulls On) playlist. Reaching the bottom of the lift to the Detention Block was frustrating as hell but I found out that rappidly crouching all the way down the lift makes you descend the lift faster and I threw a couple grenades to distract some of the enemies for good measure.
After work I plan on completing the level and from there it should be a breeze.
