In the background, an early version of the Amberbrook museum can be spotted, without some of the ruins present.
It's docked at an early version of Centennial Beach, which almost looks exactly like the location in the final game, except with a different-looking boat dock and a simpler tile texture for the yacht dock. The second one is what seems to resemble the yacht seen in the mission Salting The Earth.Again. In the final game, it is the El Hoyo Motel and no such interior exists for it. The first is the Barrio Hacienda Crib, which where Los Carnales Snatch activity originally took place in the previous game, complete with an interior that is only seen in a cutscene.
Both of them interestingly have the HUD design and some of the graphical style from the previous game, which was taken from very early in development. There are two unused savefile images for scrapped Cribs.
