The term refers to a specific build version of the game. This build number signifies a particular state of the game’s code, post-launch. The suffix -CODEX identifies the release group responsible for this package. CODEX was a well-known group in the digital landscape that would remove a game’s copyright protection (often referred to as “cracking”), allowing it to be played without purchasing a license, and then distribute it online. The v34885-CODEX release thus provides both the v34885 version of the game and the tools to bypass its official copy protection.
