I have tested it, it is not possblie. if another, whom is a better Posion zombie than me can make the jump in a private setting.. then id lauagh at them. 1 249 and a scout = impossible. No matter who is jumping. the fact that admins are the one using this spot the most and it has yet to be posted... disheartens me.
It is the most requested map on the server by anyone who is good, based simply off this particular spot. it is impossible.
