JUST A FLESHWOUND | HAB-DREYKO BYPASS MANEUVER
As of 11th Feb 2023 this exploit is still viable. Until Fatshark drops a patch to prevent you from being able to jump off that altar or blocks rescuing through the gate then you'll be able to cheese JAFW for as long as you'd like.
After repeated testing on Heresy+ you can clear a full run in 11 minutes or less with this move and it's so fast that you can even drop to one wound AFTER you have skipped over.
The 'hardest' part of this strat is bearing with the boredom you'll experience as you stay below 1 wound and sit a little bit outside extraction clearing waves for 5-7 minutes just to make sure you do spend 75% of the run time under 1 wound's worth of health. Do set a timer next to you when you begin the mission so you can board Extrac at around 18 minutes and make sure you don't overstay.
Other than that there's not much to say, make sure at least one person carries a flamer to deal with hordes on your team I guess.
