Just one of many mods that display the heister's full names in-game, but now EVERYONE has full names (of course, some of them aren't official and shouldn't be taken as canon, I had to really scrape the bottom of the barrel for some of these.)

Dallas -> Nathan Steele: His canon name/alias used in promotional material.

Wolf -> Ulf Andersson: It's probably pretty obvious.....

Chains -> Nicholas McCoy: His first name is canon established in Prison Nightmare, his last name comes from No Mercy's intro dialogue ("Paging Dr. McCoy! Dr. McCoy?").

Houston -> Franklin Steele: His canon name established in Payday 3.

Hoxton -> James Hoxworth: His canon name used in both lore (FBI Files etc.) and promotional material.

Clover -> Rochelle Maloney: Her canon name established in Payday 3.

Dragan -> Dragan Zubović: His canon name used in promotional material.

Jacket -> Richard Fritz: A pretty popular headcanon name for him in the HM community. First name is the Chicken Mask's name, last name is the name on his jacket in some promotional art.

Bonnie -> Bonnie McGee: Her canon name established in the FBI Files.

Sokol -> Sergei Kozak: His canon name established by both Prison Nightmare and promotional material.

Jiro -> Jiro Igawa: Same last name as his voice actor's (Togo Igawa).

Bodhi -> Josh Bodhisattva: First name is his voice actor's (Josh Lenn), last name is an alias used by Bodhi in the Point Break film.

Jimmy -> Jimmy Copley: Same last name as his voice actor's (Sharlto Copley).

Sydney -> Kelli King: Her canon name established in-game.

Rust -> Tom Bishop: His canon name established in-game.

Scarface -> Tony Montana: Look, I know technically he's not the Tony Montana, but everyone else refers to him as such.

Duke -> August Lindenhurst: His canon name/alias established in-game.

Joy -> Joy Futaba: More of a joke name than anything. No prizes for guessing what it's a reference to....

Sangres -> Antonio Benítez Rodríguez: His canon name established by the FBI Files.

For those wondering: John Wick's name is left unchanged, and Ethan+Hila are listed in-game as Ethan Klein and Hila Klein respectively.

(Also keep in mind the names won't appear in full when using the PDTH HUD.)
