Has anybody noticed the glitch with the Excutioner?
When he bursts through the red gate run past him and straight down till you hit the stalls and on your left you have the stairs leading to the roof tops, run across the rooftops and jump the gaps and run to the very end of the platform so you can see the barrels. The Excutioner will walk around in a circle by the barrels for aslong as you stay there! sometimes he walks a path along the building oppersite by another explosive barrel and back again. If you have a buddy watching your back you can kill him without getting a scratch
