Nice Game.
This is an interesting flash game I liked it and I found out a new tip I would like to share with you. First off destroy the camera's as said then this trick just dawned on me. Justin has to stop he could spot you when he stops but if your able to pull your gun up and shoot him fast enough you can kill him easily and have a success if your lucky with the shot. It's better than looking through random windows and getting caught by gaurds.
