What the hell kind of contraption is that?Old Longfellow

The Striker is a unique Fat Man in the Fallout 4 add-on Far Harbor.


Mark Wilson and Matthew Stevens initially conceived of the Striker's design one night after learning of their friend's medical condition. Thomas Davis, a returning crippled Navy veteran, would never walk again. One night, Mark and Matthew got to talking over shooting the balls back up the return and checking the machinery when they came up with an idea to help Thomas bowl the perfect game he was so close to. Thomas' arms still worked, so they came up with the idea of a sort of "bowling gun" built out of the ball return and a strong motor attached to a board.[1]

Their original idea would prove to be a colossal failure, as it only achieved sanding off the edges of the balls, so they began to discuss the idea with some of the old-timers. Jacob brought up the idea that they should just get and modify one of the new Fat Man catapults. Determined, they followed this advice, and used connections to find a supplier at an old surplus center out in the "willywacks," and traded a couple of tanks of gasoline for it. It was an illegal act, but they figured that it would be harmless because it was only meant for bowling.[2]

During the development on October 6, they forgot to reduce the tension springs and the first ball they launched flew straight through the wall of the office and stoved-in a table in the dining area, knocking Mr. Clark out of his chair, nearly killing him, but Matthew and Daisy were able to talk him out of suing after coming to an agreement of free games and half-priced beers for life. Meanwhile, an insurance adjuster had to be called in the next day and he also had to be convinced. Daisy spread the word that if he asked anyone, to tell them that a ball return mechanism went haywire. The Striker was effectively complete though, despite having never managed to adjust the final firing speed.[3]


A large projectile launcher, able to fire modified bowling balls by default and mini nukes once modified. When hitting an NPC, a "strike" sound effect may play, similar to how the railway rifle plays the sound of a train whistle when reloading.

Reading through the terminal entry "That was close!" on the nearby terminal gives access to the ability to make modified bowling balls at any chemistry station with the proper materials.

This weapon can be obtained in Beaver Creek Lanes. It is located in an upstairs office that can be accessed by taking the stairs up in the employees-only hallway.


  • The ability to use modified bowling balls as an ammo type is actually just a mod that can be removed and used on any Fat Man launcher.
  • The bowling balls that have been launched are retrievable, much like with the Junk Jet.
  • Placing the bowling ball launcher mod on a Fat Man with a two-shot legendary prefix (such as Big Boy) ends up "making" ammo rather than spending it, if all the projectiles that are launched are retrieved.
  • A good supply of bowling balls can be found in the bowling alley at the General Atomics Galleria.
  • The entry in the Beaver Creek Lanes terminal titled "No luck with the ball return" suggests that the Fat Man used for the construction of the Striker was found "at an old surplus center out in the willywacks," but according to General Brock's Report of September 2077 in the Fort Strong terminal entries, the Fat Man was only shipped out for use in September 2077, so it appears unlikely that one would have sat in an old surplus center since such places would usually only feature dated hardware instead of new, top-of-the-line military inventions.
  • In one terminal entry, an employee states that he feels that what they're doing is "not entirely legal," but defends the weapon by stating that they're "only gonna kill pins with it, so what the hell right?"
  • In another terminal entry, it is stated that there was one incident with testing, when a modified bowling ball crashed through the office wall and into a customer's table in the dining hall, almost hitting him. It is stated in another terminal that this man didn't sue them since he understood it was an accident and was compensated for the incident by having "All of his games and half his beer tab" for free. It was also stated that after the incident, the dining area was closed off.
