Next weekend i'm going to be going for Halo ce under 3 hours, anyone care to join me? to make it easier grunt funeral and boom skulls will be on. (as well as some other misc beneficial skulls. TBD) We can swap skulls out between missions if one makes it easier or harder.

Keep in mind that you need to complete all levels solo on legendary in order to get the achievement.

Anyone who can reliably perform the hanger bay skip on truth and reconciliation, or the assault on the control room skip (dem slippery cliffs don't like me.) or the keyes bump skip will be given priority. I already have good times on those levels (except for T&R, which is like 1 1/2 hours) but i don't want to have to sit there looking like an idiot failing the keyes bump for 4 hours again.
