What Goes Around
- Use the stun gun on Joe and Josef before killing them
When you reach the location, park a small distance away and equip the stun gun. Shoot Josef with it (he is the one holding a gun to some hapless people) and then equip a gun with proper bullets to finish him off.
As you approach the barn, Joe will come flying out of it on a tractor. You can quickly shoot him before he drives past (it’s quite hard to do as he is moving pretty fast) or stop him and then shoot him with the stun gun before finishing him.
- Kill Joe and Josef before they leave the farm
Josef is easy to take out as he stands his ground for a fair while, giving you time to shoot him. Joe on the other hand, is a bit of a pain because he rushes off in a tractor the moment you get near the barn.
After killing Josef, slowly walk up to the parked tractor off to the right and climb inside. Drive towards the barn and Joe will appear. For some reason, being in a tractor will cause Joe to stop, allowing you to block his escape. This is your chance so quickly jump out of the tractor and stun him. Finally, finish him off however you see fit and enjoy the sense of satisfaction at a job well done!
