That last one was a great kill.
Yeah man, it’s all the same battle - but man if you time the shot the propane ignites.
Gonna try a few next few weeks.
Are you saying it’s possible to ignite the Reaper’s gas cloud before he detonates the thermobaric attack? 
Yeah man, did you not watch the end of the video?
Yes I did. I just thought the last grenades hit him at the same time as he self-detonated, by coincidence.
No it ignites hence the ridiculous mushroom cloud.
If you look earlier - you see when I’m on the rock - there’s a split second where he powers down, shields go down - then the propane booms. It’s a small window - but it can be done.
Allright. I’ve only killed 1 Reaper, since I’m currently playing another game. I got the impression that the Reaper always goes out by self-destructing with a thermobaric attack. At least I shot at his components until he finally unleashed 1 final thermo, that killed himself as well. I may be wrong of course.
