Flak

 is a former slaver from Paradise Falls who now lives in Rivet City with his business partner and lover Shrapnel. Together they run the Flak & Shrapnel weapons store in the Marketplace.

He is one of the targets for enslavement that Eulogy put a special bounty on. According to Paradise Falls' gatekeeper, Flak sold the slavers out to Rivet City in order to gain shelter there. Before enslaving him, Flak is unkillable. This ensures that there will always be at least one live target for Strictly Business.

In order to reduce the injury incurred by enslaving Flak lock pick the door to his and Doctor Li's room after 12am, if Flak is in bed activate a Stealth Boy and fire the Mesnetron at Flak while he is asleep, he will awake and the enslavement dialogue begins. When I did this, Dr. Li was standing right next to Flak and remained neutral, however the Security Staff become hostile, by exiting Rivet City as quickly as possible without firing on anyone and fast travelling to another location and then back to Rivet City will return the Security Staff to a neutral stance. This worked on the Xbox version. After having done this and playing for a few hours every time I go to the Marketplace in Rivey City Flak & Shrapnel's store is unmanned!

Flak and Shrapnel share their store's inventory, so buying or selling from either one of them will update both of their stocks. This means that if Flak is enslaved by the player for Paradise Falls, Flak and Shrapnel's store will still be open. They consistently have a larger amount of caps than the other shops in Rivet City, making them prime sources of cash in exchange for unneeded loot.

Flak can also repair the unique Alien Pistol.

Appearances
 only appears in Fallout 3.

Bugs

 * If Flak is enslaved and the player is not successful in subsequently removing the collar to free him, this will cause Shrapnel to disappear from Rivet City and no trading will be available.  Observed on PS3 and Xbox 360 version 


 * Shrapnel may start patrolling between Paradise Falls and Rivet City, trading is still possible.


 * If the Mysterious Stranger kills Flak, he is dead. Not unconscious...dead.


 * If the player chooses to enslave Flak and then releases him from Paradise Falls, he may be found back in Rivet City doing his usual routine. The problem is he is now missing his dialogue options. When interacted with, he will just have a line stating "You saved me from those bastards. I won't forget it." Shrapnel will also mysteriously disappear. This can be fixed by using the "removefromallfactions" command on Flak. On the Xbox version, I freed Flak after enslaving him and when he returned to Rivet City, he wouldn't speak to me at all. Not even the dialouge mentioned by the previous User, he just keeps shifting positions everytime I press A. Its troublesome since he's usually the one manning the shop while Shrapnel is elsewhere.


 * For long periods of time and a lot after Doctor Li moves to the Jefferson Memorial, you will find Flak trapped in Li's room behind an Average lock with Shrapnel waiting outside. He will not leave until you break in and shoot him which of course makes everyone in Rivet City start gunning for you. (Seen on Xbox 360 and PS3 versions so far)


 * If ANY follower, (ex. Charon, Clover) kills Flak, he will die.
