Agony Unrated Update 5-codex [portable] Access
Beyond the new content, Update 5 was a maintenance patch. The update file was relatively small, coming in at approximately 228 MB. The description from CODEX on the release page indicates it functioned as a cumulative update, requiring players to have previously installed the base CODEX game and updates 1 through 4. This suggests the patch contained not only the Cherub models and behavior scripts but also a collection of smaller bug fixes and optimizations aimed at improving the notoriously unstable game. This update aimed to deliver the UNRATED content with the highest level of stability and polish that Madmind had managed to achieve post-launch.
