Back in 2014, Hello Games’ Sean Murray acknowledged in a Game Informer interview that official modding tools were practically a must for No Man’s Sky. “I almost feel like we need to give them the [modding] tools; otherwise then they’re just going to start making them, tearing apart your game,” Murray said at the time. “That’s what I have more of a fear of.”

Fast forward to today, and some PC No Man’s Sky players (who can manage to get the game running) are indeed just tearing apart the game to make their own mods. Despite the current lack of official mod tools, players are extracting game files and tinkering with them to create unsupported mods just days after the game’s PC release.

This short video outlines the basic process used to create these unofficial mods. Interestingly enough, the PC version of the game seems to be built on top of a host of files in the PlayStation Archive format, though they’ve been renamed to the more generic PAK extension for Windows. Regardless, these files can be uncompressed using a PSARC decompiler tool, and then edited and recompiled to get a modified version of the game up and running.
