First half of the run: I sleep. Second half of the run: Oh shit.
Tips and possible time saves: You can do a sharper turn at 1:37 by getting closer to the rocks, looking at the same direction as I and 'taping' right (D on keyboard). When passing trough the tunnel that leads to the Devil's House, call D-Walker when Ocelot says "There's a lot -". When you down the Man on Fire get on D-Walker and shot him with the fulton ballista as son as the Floating Boy teleport sfx plays.
The water pistol I used: Base: WATER PISTOL (GRADE 5) Magazine: 12GA MAG x6
00:01.217 - Run starts (last dark frame) 02:32.868 - Load 1 starts (cutscene starts / camera angle changes) 02:51.634 - Load 1 resume (last dark frame) 03:31.401 - Run ends (lose control of Snake / camera angle changes)
If there's something wrong with my timing I'll fix it as soon as possible.
