How to play the alien bunker content in GTA 5 that Rockstar left behind

GTA 5 features plenty of content that can keep players busy for hours on end. However, a few elements that Rockstar Games decided to cut from the title's final version for unknown reasons have surfaced over the years. Recently, a beta version archive (of the PS3 build) was leaked online, providing a glimpse of an alien bunker that isn't a part of the official version.

Modders have made it accessible on PC for both the Legacy and Enhanced ports. This guide explains how to play the alien bunker content in GTA 5 that Rockstar left behind.

Note: Mods are third-party add-ons. Readers are advised to use them at their discretion.

As mentioned, Grand Theft Auto 5's leaked PS3 beta build showed an unfinished alien bunker under the Fort Zancudo military base. However, the asset is unplayable in its original form as per Antasurris, who was the project lead for the mod in question.

They stated that the leaked version had incomplete collisions, missing textures, and lighting, among other issues. As a result, along with several other modders, they carried out a modding project that included reverse engineering, PS3 format conversion, patching, scripting, and various other fixes to make a restored version of this cut content accessible.
