The 1.0.877.1 era was part of a timeline where Rockstar temporarily banned the use of mods in the single-player campaign, only to later relent following community backlash. Script Hook V stood as the resilient tool that kept the single-player modding scene alive despite these corporate hurdles. It demonstrated the resilience of the PC gaming community and the demand for user-generated content.

Even with this safety feature, you should never take the risk. Rockstar Games has a strict anti-cheat system that actively scans for modifications. If the anti-cheat detects modified game files while you're online, your account will be permanently banned. Script Hook V is specifically designed for single-player modding and should only be used in Story Mode.

For mod developers, this version provided a more powerful and stable platform, allowing them to create complex mods with greater confidence. The ability to access entity pools and more advanced native functions meant that mods could be more ambitious and integrated with the game's core systems than ever before.

With every update Rockstar released, the game’s executable file changed. Memory addresses shifted, and code structures were rearranged. Consequently, the previous version of Script Hook V would cease to function. The release of Script Hook V compatible with 1.0.877.1 was, therefore, a moment of relief and excitement for the community. It signified that the modding scene would survive the latest patch, allowing players to enjoy the new official content while retaining their custom modifications.

Released in alongside the Smuggler’s Run update, version 1.0.877.1 introduced:
