Wow, I haven't checked this thread in a long time. I can't believe it took almost three years for someone to beat my time, wtf. Congrats Jagger. You can have it. :V
First sector 1 and sector 2 visit were decent I guess, but then things got out of hand: I went into autopilot mode at the Nightmare segment and had to travel all around sector 2 again, because I missed the seeker missile door- cost me 3 minutes lol. Other terrible things that happened: got the stupid Nightmare II phase ( -.- ) and died to Phantoon pretty late into the fight (easy everytime). A lot of other things could be improved and I kind of feel that my next good run should get under the sub 4 hour mark.
