The Well Stacked Pizza Co. was originally meant to return but removed before release. Outside Pizza This, the logo can still be seen and employees in the Alderney branch have "Well Stacked Pizza Co." on the back of their shirts. This may also indicate that this was once the original location for one of the stores.

Niko would originally bring prostitutes to his home.
There were two deleted cheats : the first one gave money to the player, it was probably "729-555-0100" ("729" for "PAY"); the second one made the game advance the time by one hour, probably something like "???-555-8463" ("8463" for "TIME").

There was a helicopter with only two propellers, and a design which looked just like the Police Maverick but with no LCPD logos on the side.
