So I did my first heist with three random people, the prison break one. No mics, but we did quite well. Went through all the missions and only failed twice. Then in the final mission we were all done and all we had to do was parachute out into the water and get into a chopper. I have not parachuted or swam on the PC version. Got instructions on how to open my parachute mid air. But I drowned in the water. Thankfully it was the first death of the mission, or everyone would have been pissed
We should try to get a heist going some night.
TL;DR: Finished entire heist, I almost ruined it by drowning at the end.
