In GTA: Liberty City Stories, the Helicopter (referred to as Tiny Invisible Heli in cheat devices) refers to a variant of the normally unobtainable NPC Police Maverick. Like the regular Police Maverick, the Helicopter is also unobtainable. It is similar to the regular Police Maverick, but it has tinted windows - regular Police Mavericks spawned using a cheat device, however, have transparent windows.
The helicopter appears once the player obtains a 3-star wanted level, the helicopter has an "invisible" 5.56mm machine gun on the fuselage (similar in both sound and power to the M-60), as well as a searchlight, and a loud speaker (used by the police to address the player from the skies).
The helicopter can also airdrop SWAT units on ropes. The Police Maverick flown by the police is actually a special type of vehicle controlled by the script - it is free to fly anywhere - even through buildings - without a chance of crashing either.
The helicopter is only intended to appear during police pursuits. If it is spawned otherwise, it appears invisible and crashes the game upon entry, although the player can use cheat devices to take it to a Pay 'N' Spray, where it will become visible again, albeit without rotors. A more difficult method is to use cheat devices to steal the helicopter while it is pursuing the player. This is much more difficult, but once done the helicopter will retain its special abilities - the player can use it to fly anywhere, even through buildings, above the game's height limit, under water, or outside the game's boundaries.
When spawned using a cheat device, the Helicopter performs exactly like a regular Police Maverick. However, if it is stolen with cheat devices, it retains its special abilities, and is thus extremely responsive and fast - it can accelerate to full speed and stop in the blink of an eye. It can also accelerate upwards very fast, past the game's height limit without any limitations.
- The helicopter has no blades, has breakable tail and will sink in the ground when landed, making it explode. It is similar in this manner to the unobtainable NPC helicopters in GTA VC and GTA III - although in GTA III the helicopter will be visible, although unenterable, when spawned.
