Completing Control's paid DLC, 'The Foundation,' can take players approximately 27 to 28 hours. This estimate includes finishing all main missions and a few shorter side stories, along with some exploration for health and power upgrades. If you focus solely on the main story, the playtime drops to an estimated 24 to 25 hours, though an extra hour might be needed if you encounter difficult boss fights. For players aiming for 100 percent completion, including all side stories, upgrade points, leveling areas, collectibles, and unlocking outfits, the total playtime is estimated to be between 37 and 43 hours. The game generally guides players toward necessary objectives, with most collectibles found naturally during gameplay.
'The Foundation' DLC features 23 main missions divided into six categories. The core objectives involve searching for Dylan and defeating Resonants, which are ongoing throughout the playthrough. The main story acts progress through distinct phases: Wake Up, Contain the Crisis, Protect the Dimension, Defeat the Hedron, and the Epilogue. In addition to the main missions, there are 18 optional side stories. One particular side story near the end of the game is strongly linked to overall progression and is highly recommended for a smoother experience, potentially preventing players from getting stuck.
