Grand Theft Auto: Liberty City Stories (PSP)

Released in 2005, Liberty City Stories is a prequel to GTA III taking place in 1998 and starring Toni Cipriani. Though a fair number of content was scrapped, surprisingly, most of it can be accessed via trainers.

Unused Vehicles

 * DeadDodo: The Dodo plane that is always in the air back in Grand Theft Auto: Vice City is in this game. The DeadDodo is mentioned in handling file and and can be spawned with third-party trainers. However, simply spawning through it without further modifications will crash the game upon spawning.
 * Toyota Supra: Interestingly, a Toyota Supra is listed in text files. It is unknown what its in game name would be (assuming it would be changed).
 * Subaru Impreza WRX: Just as interesting, a Subaru Impreza WRX is also listed in text files. It is unknown if this would be its name if it made to the final.
 * Dodo: Unlike the DeadDodo, this one will not crash the game upon spawning. However, it has no acceleration, making it undrivable.
 * Hunter: The Hunter attack copter is in the game, but never even seen. It can be spawned with trainers and its weapons are working.
 * RC Goblin: The little toy copter from Vice City was to return, but was cut. It can still be spawned with trainers, but a mod needs to be installed to control it.
 * RC Raider: Another toy helicopter that was cut. It can still be obtained through trainers.
 * VCN Maverick: No idea what it's doing in Liberty City, but it can be obtained with trainers. However, it has no acceleration.
 * Bus: The Bus from GTA III was meant to return, but now it can only be spawned with trainers

Unused Weapon

 * Tear Gas: Not available normally, but can be obtained through trainers.
 * Ruger: HUD icon and texture can be found on the PS2 disc. Scrapped early in development.

Unused Coast Guard quotes
Police boats are in game, but never used by the LCPD. However, unused quotes for the coast guard can be found in the files.
