Due to sloppy slide jumps in the courtyard, a failed nade boost in the ending hallways, bad hallway movement in that I wasn't jumping to hit my head on the ceiling as much as I should've, and not getting the most ideal plasma drops which would've allowed for faster brute kills and an extra nade boost, I'm pretty confident that this can go down to be as low as 1:44. This is a 1 second improvement on the previous record I held, which is still a good time but there's a lot of room for improvement.
