Hi guys I would really like help with that 
I need to complete them both in 37mins, but I can get better in other levels, on these two I can’t 
It’s Halo 2, you just have to get lucky. Doesn’t matter if you know all of the tricks and can execute them all flawlessly, if the RNG doesn’t want you to succeed, you won’t succeed. Everything is RNG, from enemy awareness to accuracy to spawn patterns and even damage. If you don’t get blessed by RNG-sus you won’t get anywhere.
I got to the Shadow tunnel on Outskirts in about 5 minutes and kept running the correct path flawlessly over and over again for another 18 minutes until the RNG finally let me through. So much for that speed run. I just gave up on Halo 2 Legendary speed running after that.
I know man I’m frustrated too. And it’s just ridiculous that 343 needs it completed in 3 hours, the same time that they need for the other Halos which is just easy!
Do you need to do 37 minutes each or total?
I still need to complete.gravemind in about 40 mins or less. Im up for it. Gt is ericdk
If you get speed run Gravemind in 37 minutes even on a segmented run, your a god.
(hint, co-op turns iron skull on. Do it solo so you can do the despawns)
