This is a bit contradictory to what has been reported in the past, as the previous claim was that it would take about 13-15 hours to beat Shadow of the Tomb Raider's story.

If one decides to tackle all of the side quests, hidden collectibles, and conquer higher difficulty settings, it seems likely that will take another five to 10 hours, so between 15-20 hours total. When we completed our initial playthrough, we had played between eight and 10 hours with about 60% in-game completion. When playing Shadow of the Tomb Raider on normal difficulty and ignoring most side content, players can complete the main story in a little less than 10 hours. Releasing in the midst of the Fall gaming rush, budget-minded gamers may be wondering exactly how long Lara's latest adventure is before they commit to buying it, and after playing through the game ourselves, we have a definitive answer.

Shadow of the Tomb Raider, the final chapter of Lara Croft's origin story that started with the 2013 reboot, will launch this coming Friday, September 14.
