3:45 before I am below the 3 hour mark. Trying to avoid The Ark, the scarab part completely kills my run. I'll probably do Halo because I know I get it that done faster because I lost a few minutes when I had did it earlier. I accidentally jumped off from the top floor of the control room enterance and had to walk all the way back up again, and I messed up once on the warthog run but I can fix that too. Did Cortana in 15:10 first go, pretty proud of that. Tsavo highway is a nightmare to speed run. So many random elements to it.
