Hi.

Since I've always wondered how would the hand holding exactly work in GTA SA, as seen on this picture:

(curse the Google!)

This also includes how it is possible for peds to back up slowly while shooting (this includes backing up while crouching). 

I think this should be possible to be in multiplayer scripting as well. Pretty sure there are more animations that "aren't in libraries", for example hand holding (I have never seen this in any anim library, but maybe I'm wrong).

Thoughts, questions, comments?

That's a very interesting question. It begs the question on wether handholding is strictly an animation or something else deeply scripted into singleplayer SA - As peds can be seen handholding while doing other body-wide animations besides just walking in a straight line.
