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's computer 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 (MP-10) against the player. It is also the weapon they use for drive-by shooting. At five and six stars, FIB agents begin to use the much more accurate and powerful carbine rifles (M4), while some agents may use combat shotguns (Remington 11-87) or pump-action shutguns (Ithaca 37).
The agents employed 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.
Grand Theft Auto: Chinatown Wars
In GTA: 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 Buffaloes, they drive black FBI Ranchers, which have similar design to Cavalcade SUVs 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 high speeds, 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.
Grand Theft Auto V
Current information about the game's FIB is mostly unknown.
Employees and Associates
- Agent Jones works in Liberty City as of 2008. He is involved with the cases of Elizabeta Torres's drug deal and The Lost Brotherhood.
- The Contact works in Liberty City for a government agency known as United Liberty Paper. He claims that the U.L. Paper is not part of the FIB, although he may or may not be working with the FIB.
- Michael is a succesful bank robber who retires from his "job" after the FIB offered him a deal, which he got rich off.
- The FIB is based on the FBI. The agency's name is a play on words since fib is a synonym of lie, which probably hints towards corruption within the organization.
- In Grand Theft Auto IV, some of the characters, particularly those in the Pegorino Family strand of missions, usually refer to the FIB as the "Feds", which is a general slang term for the FBI (or in this case, the FIB).
- On being asked by Niko at their introduction if U.L. Paper is actually FIB, the contact replies sarcastically asking if he looks like a homosexual, which might be a reference to the semi-confirmed homosexuality allegations of the FBI's first and longest serving director J. Edgar Hoover.
