*** Spoiler - click to reveal ***
- Go Find Irwin on the map. He is a highwaymen inside man who the twins have pissed off so he's willing to help out Prosperity. The first mission is to kill this guy named Frank. He is the warden at the jail. You'll have to stash your weapons, hop in the back of Irwin's prisoner truck, and Irwin will drive you to the jail.
- Once at the jail, follow the guards to the bullet manufacturing room. You will create bullets for about a minute or two and then your shift will end. (Where can I find this job that requires this little of work?!?!).
- Once your shift is over, you will be forced to walk into the yard. You can finally stray the course a little once in the yard as the travel paths no longer become linear. In the middle of the camp ground there should be a guy sitting near a fire. Go talk to him and he has some plans of escaping the jail also and will give you some hints about things.
- At one side of the yard, you will hop over some objects and go into a little shed where you can find a Shiv. *Note* you must talk to the guy in the middle first otherwise you can't pick up the items* Once you have the Shiv, Go back to the yard.
- Now if you walk diagonally through the yard to the other corner from where you got the Shiv, you can climb outside the yard again. There is once again a little shed, but there is an enemy in here so make sure to stealth kill him to not alert anyone. Grab the key from the shed. You now have the two objects you need from the yard.
- Make your way back inside by coming through the elevator that originally brought you to the yard. You will now make your way through the jail. Make sure you stealth kill the enemies, and in some scenarios you may have to move the bodies out of plain sight if there is more than one enemy around. You will make your way up to the roof where you will eventually be able to kill Frank.
- With Frank out of the way, go back to Irwin's truck in the parking lot, and he will drive you away. Talk with Irwin when you get back to his spot, and he will have you meet him at a gas station later on. Once again stash your gear in the yellow bag, and Irwin will come back at night with a car (happens when you stash your gear). Now it's time for the demolition derby.
- Drive into the arena and the derby will start shortly. You're allowed to use a side weapon to destroy other vehicles. I had the grenade launcher as my secondary, so this made it extremely easy to beat this part as it one hits all vehicles. *If you want a little of a challenge I wouldn't bring the grenade launcher as it was literally so easy and almost not even fun. * Destroy all the cars and kill all the enemies in the ring and congrats you won the derby. Follow the marker and make your way to the dinner table with the Highwaymen Capos are all seated. (Don't skip this scene if you're a scene skipper, as this is a pretty bada$$ one). Joseph's son will come in abruptly and take the twins away from the room, ending the cut scene. Go to the bathroom, and pick up the weapon from under the toilet seat. (Mine was in the second toilet). Go back in and kill everyone in that room, and then escape the derby area.
- You now need to head to New Eden where you will finally be able to fight the twins. One has a flamethrower and gets up close in personal, the other has a sniper. I dealt with the sniper first because she was doing a ton of damage to me. Kill both the sisters (they're a tad stronger than an enforcer) and the achievement is yours.
*I Would highly recommend having an LMG, assault rifle, and either a sniper or SMG as you will need high damange weapons for this fight*
