At the ports in the south of Los Santos, various ships can be found. Players have been pointing out the similarities between some of the boats in the harbor and the boat used by Niko to go to Liberty City in GTA IV. One of the ships is named the Octopus, which some fans have theorized is related to the boat from the introduction of GTA IV, the Platypus, as they are both aquatic animals.
The Grand Senora Desert
In the desert, if the player chooses to look at nearby homes, they can find "wanted" posters, usually on a table or on the porch. Same poster was used in advertising GTA IV before it was released.
- In the mission, Casing the Jewel Store, Lester mentions an "eastern European kind of guy making moves in Liberty City." Niko and Roman are of Serbian descent, so many fans put Liberty City and eastern Europeans together to form a claim that Lester is referring to the Bellic cousins.
- Niko Bellic has a LifeInvader profile that the player can interact with to an extent assuming they have a next-gen version of GTA V.
- Niko Bellic is an eligible father in GTA Online, however this is non-canon.
- Packie McCreary can be used as a heist member in GTA V. When the player picks him up he will reference to Niko. He also references to Niko when recurring the events of Three Leaf Clover, while on the drive to the Paleto Bank for the mission The Paleto Score.
