Invisible Barriers, also known as Invisible Walls, are preventative measures integrated into the game to prevent the player from leaving the game world. This feature can be found in 3D Universe games and above. They kill the player in a variety of ways, from just blowing up the player in a boat, to taking a wing off a player's jet. There are three types of ways the player can be killed by the barriers.
In GTA IV, a vehicle will explode after only a few miles from shore. Messages will pop up on the screen, taunting the player to return to Liberty City. In Grand Theft Auto V or GTA Online it actually isn't an invisible barrier, but if the player flies an airplane as far as possible in any direction, after a while, one or both of the plane's or helicopter's wings will suddenly get torn off the plane's fuselage, making it plummet down into the ocean. A boat will simply cut off, and begin gliding toward the ocean. The creators of the game, in that sentence, made something different than from other HD GTA games. If the player exits the plane unharmed and is floating in the water, after some time, they will begin losing health and will eventually die. Similarly, if the player bails out of the downing aircraft and deploys the parachute, the player's chute will disappear, causing the player to fall to death. They will hit the water's surface at full speed, killing them instantly. If the player makes it to the water, sharks will spawn and try to kill the player. Finally, if the player tries to use a Kraken Submersible, the Kraken will short out, and sink below the bottom of the ocean, and since the engine can't recognize you when you're below the world, exiting the kraken will simply teleport the player back to the nearest island/land.
