Federal Investigation Bureau

The Federal Investigation Bureau (FIB) is a Law Enforcement Agency in the Grand Theft Auto series, appearing in Grand Theft Auto IV, Grand Theft Auto: Chinatown Wars, Grand Theft Auto V, Grand Theft Auto Online and Grand Theft Auto VI.

General
The FIB is based on the real-life Federal Bureau of Investigation. It is suggested that, just like the real-life FBI, he FIB has the role of an internal intelligence agency and a federal criminal investigative body. As seen in GTA V, they also do domestic surveillance and counterterrorism.

Events of GTA IV and EFLC
The FIB makes its debut in the series in Grand Theft Auto IV.

With the wanted level system in GTA IV has been changed, FIB officers appear at four stars, unlike their 3D Era counterparts who chase the player at five stars. At four stars, small groups of the FIB officers will arrive to assist the LCPD and the NOOSE. Their attacks will become more frequent at five and six stars.

FIB agents drive their own variant of the Bravado Buffalo; this variant has a unique black paint job, complete with the LCPD'sCOMPUTER SYSTEM which has full access to the department's database and blue/red emergency lights. The FIB agents are expert drivers, and would doggedly follow the player. They are also capable of drive-by shooting.

At four stars, most FIB agents will use SMGs against the player. It is also the weapon they use for drive-by shooting. At five and six stars, FIB agents begin to use much more accurate and powerful Carbine Rifles. The FIB also make use of Pump Shotguns, and their standard sidearm is the Pistol.

The agents employed by the FIB are often late middle-aged Caucasian men, unlike the LCPD and NOOSE who employ young to middle-aged Caucasian, African-American and Hispanic officers. These agents wear different types of uniforms; some wear random clothes with a navy blue jacket with the FIB logo, while others wear black suit pants with a white shirt and a black combat vest and a badge around their neck reading "FIB". All FIB Agents carry their FIB badges on the neck.

In certain missions in both The Lost and Damned and The Ballad of Gay Tony DLC packs, the FIB Agents employed are of African-American, Caucasian and Asian descent and wear different apparel, such as suits and ties, overcoats, blue FIB track coats and others who wear a tactical vest with the letters "FIB" printed in yellow on the front and the back. In TBoGT, the FIB agents may use Automatic Shotguns and Assault SMGs.

Events of GTA Chinatown Wars
In Grand Theft Auto: Chinatown Wars, the FIB agents wear grey outfits. After gaining a four stars wanted level, the FIB will be dispatched to the area to assist the LCPD in killing the player.

Instead of driving FIB Buffalos, they drive black FBI Ranchers, which have similar design to Cavalcades with modified headlights and grilles. Due to the fact that such law enforcement vehicles don't usually skillfully chase the player, or even follow at all at highSPEEDS, the FIB can be easily evaded due to their slow FIB Ranchers. However, unless the player gets rid of the Wanted Level stars, there will be just more FIB Ranchers spawning in front after they're evaded.

On foot, FIB agents carry Micro SMGs (same weapon as the NOOSE officers). The FIB Agents attack the player in similar ways as NOOSE officers do.

Events of GTA Online
The FIB appeared in certain missions in GTA Online often appearing along side police.

There are different skins, one with a blue jacket with 'FIB' decals which look like the FIB agents in GTA IV, and another with a suit and tie and a blue bulletproof armor with 'FIB' decals. They can be selected in Capture Creator. With the Last Team Standing Update these agents have been replaced by IAA actors for some reason. However, they were added again with the Heists Update alongside with new options such as the aircraft carriercrew or the Merryweather operatives with night vision from The Humane Labs Raid.

They also make an appearence in the heist setup mission Humane Raid - Key Codes. When they try to lurk the crew of GTA Online Protagonists while they are recovering key codes for The Humane Labs Raid.

Events of GTA V
The FIB returns in Grand Theft Auto V, playing a major role in the game storyline. The Bureau has headquarters located in a high rise office tower located in Downtown, Los Santos. It's based on the One California Plaza. The FIB is a prominent antagonistic faction in the game along with Merryweather.

Unlike GTA IV, the FIB will not pursue the player if he has a 4 stars wanted level, being replaced by NOOSE units. The FIB makes regular appearances in missions. Three corrupt agents, Dave Norton, Steve Haines and Andreas Sanchez are associated with the three protagonists and give them several'JOBS' such as heists and attacks against theIAA.

It appears that the FIB has a rivalry with the IAA. It mirrors the real-life rivalry between the FBI and the CIA/NSA.

Events of GTA VI
In 2015, The FIB are now allies to the five protagonists as they help them set up various heist missions across the majority of San Andreas to help them stop the IAA and Merryweather. Dave also made Michael a special agent in the Bureau.

Agent 14 a supposed special agent in the IAA is revealed to be a double agent working for the IAA.

FIB Tactical Team
A unique FIB tactical team appears in the GTA V storyline. They use the same model as the NOOSE officers, but with FIB decals on their vests rather than 'POLICE' decals, indicating they are independant to the LSPD and are under the FIB's command. It is based on the real-life FBI SWAT. It is suggested that they are dispatched in case of extreme situation (hostages, etc.), however in GTA V they are seen defending the FIB Headquarters and raiding areas such as the Kortz Center on FIB agents' order. They are seen only in The Bureau Raid (roof approach), The Wrap Up and The Third Way (where they use the NOOSE model), and they can be selected in Capture Creator.

They use better weaponry, such as assault rifles, SMGs and Shotguns. They share tactics with the NOOSE. The only known vehicle they use is the FIB Granger.
