Updated run from my 2:24 pb. Incorporated 2 major sequence breaks and overall better movement.
In testing the helicopter auto-scroller I realized that the blow up all vehicles cheat code could bring the helicopter crashing down and skip the usual sequence. The helicopter Itself is immune to all forms of traditional damage so in order to destroy it without cheats I used the dance menu to gain control of the initial cutscene and lit myself on fire whilst entering the heli. This was a little tricky however as too much damage will blow up the helicopter prematurely and fail the mission, too little damage on the other hand and the heli may survive the damage and/or could crash land much later into the auto-scroller. It appears from my testing that cj himself has to be submerged in water with the helicopter for the sequence to break so I tried my best to crash land in the first available stretch of water.
For the rest of the mission I was able to use 2 jetpacks to move around as the time I saved from the auto-scroller skip made it so they wouldn't despawn from expiry. A massive thanks to Rhans' tutorial on having multiple menus + an active RC Baron • "Active" RC Baron + Dance Menu + "Nor... . This allowed me to use the dance warp + weapon menu for the pistols + Baron for the remote detonation of the snakehead.
Also messed around with new fps capping. Limited the frames to make the swimming faster and having higher frames seemed to help me reliably catch fire more often. Strangely though when I have the dance menu active the game forces me at 25fps.
