How do you kill Jigsaw??????!!!!!

Ok you have two ways to do this One is wait around for an armored gaurd to come around, kill the bastard quickly, and hell drop a remote controlled mine that you can pick up. Once you have the remote controlled mine set it up so that jigsaw walks by it then blow it up...But that takes too long.

My way is this.

Dont wait around for the gaurd, look around in corners of the roof for a remote controlled mine ( there is one all the way on the far upper left side of the map behind the door one of the gaurds comes out from it) Wait there and fill up on remote control mines, they ll respawn after about a minute or two letting you grab up to about 10. Now once your all filled up on remote mines DO NOT RUN AROUND AND TRY TO LEAD JIGSAW, Get up close and personal with him, throw a mine at his feet, now you can set it off or let him shoot either way itll still get the bastard, once you set a mine off near him itll blow him back a bit leaving him stunned, once he is stunned and if you stayed clear of the blast you should be able to run up and set another right next to him and set it off. but wait till he starts to walk around or it wont work. Just keep repeating it until hes dead. trust me it will be a lot easier than running around the place and haveing him shoot the f@cking things as soon as you set them on the wall youll take some damages, but you should be able to eaisly dispatch him before they get the better of you.
