Split Jack

 is a character who is added to Fallout 3 in the add-on Broken Steel.

He is the leader of a group of bandits which is plaguing the water caravans going from Rivet City to the Capital Wasteland.

Once his name and location has been revealed, the Lone Wanderer can choose to either kill his whole band or replace him by challenging him to a duel with predefined weapons. Additionally, if you have a high enough Speech, you can persuade him to stop high jacking water caravans.

Tips For Defeating
- If you choose to challenge Split Jack, you will be forced to fight him with three weapons of his choice: the Knife, the Lead Pipe, or the Nail Board.

- The nail board will break eventually, making it an unfit weapon, as anything but, will get you shot.

- It takes a large amount of fighting to kill him, given he is wearing metal armor, and during that time his gang members will get very close to the action. If you should strike any of them accidentally, they will once again turn on you with guns.

- If the player can trap him in water, or continue to walk backwards keeping the rest of the gang at a distance, it will keep the action one on one.

- Lone Wanderer must be careful using vats if they have the Mysterious Stranger perk. The Mysterious Stranger could appear, causing a humorous situation where he will gun down Split Jack, and often half of his gang standing in the way.

- It should be noted that while not impossible by any means, defeating Split Jack can be time consuming. Drugs like Psycho and Buff-out can assist in the process.
