also did a no strat no death one but cyborg arena which is the real hard one lol
the other thing is speedrunning off yourself is more than just that
you need to find the right time to die while doing stuff so you can spend your last life and win as soon as you finish the objective
personally i think extraction is just garbage time where nothing happens
either one of these 3 happens:
1.you hide in some place that the scouts never detect you and you idle for 3 minute and get out when the extraction comes
2.they raise an alarm and you shoot stuff for 3 minutes
3.you die for 3 minutes and keep reinforcing then get on the ship
as for splitting off,i think you can already do that without the extraction part,for dropbase AIR base,it would be one guy for dropship,another guy for drop ship 2,the last 2 guys go for the airbase itself
adding in extraction would just means either
1.someone who finishes drop ship early and go to extraction and call the shuttle
2.assign someone to camp and call the extraction shuttle
there are many categories so i am not concerned by longevity,but those are just my personal thoughts
and no completing the mission is not optional
actually landing right outside of the objective and OBI laser the drop ship would be faster since you dont get instantly blown up
but i think the fastest might be direct land on the air base and rush the objective somehow,then blow up the airships
pretty slow but did one at 10:49(drop ship)+17:26(icbm)+8:32(arena)=36:42
