Basicly, no
The chainsaw you needed to hold it on a person for ages..
And I think that was just a bunch of really short lived bullets (And weak, by the look of things) that would only get a chanche to travel the length of the blade..
Acctualy, I don't think that was how it was done... Maybe that can be be done?
I have no idea how the chainsaw worked
But, OFP really isn't a game that you could use blades of any kind in.. You ever tried walking up behind an enemy? They always notice you
Dunno if the short-lived bullet idea would work...?
