no pics, but try it with a friend in a private if you don't believe me.
To test this for yourself:
1) start a private match with atleast one friend as an infected and atleast two as survivors
2)kill ALL the AI survivors (if any)
3) incapacitate one of the two human players
4)walk up to that incapacitated survivor and hold "X"
5) the "reviving teammate" bar will pop-up, hold this until they are back up on their feet.
if I lied then may satan himself slap me silly with a wet newspaper
EDIT:
not tested on PC, but it probably WILL work. I think it may have to do with the latest L4D update. dunno
