"Sonic Lost World-CODEX" refers to the scene release of the 2015 PC port of the originally 2013 Wii U title, which allowed for 60 FPS, high resolutions, and DLC inclusion. The game features parkour-inspired movement and a story requiring roughly 7.5 hours for completion. For the most stable experience with cloud saves and achievements, the official release via Sega is recommended over scene releases.
