I'm grim_reaper but i couldn't get into that account which i don't know why but anyway. I achieved a heel power attack resulting in arm and pec dismember.

Here's how to do it: (Couldn't find my replay anywhere)

Press C
contract left pecs
raise both shoulders
Extend right pecs
right rotating chest
space x3
lower right shoulder
grabby hands
space x2
extend both hips
contract both knees
contract both ankles
press p

That's all , have fun!

Tell me what you think. The grim is back!
