It will take 17 – 20 hours to beat Marvel’s Spider-Man 2’s main story and see the credits roll. Additionally, it will take 25 – 30 hours to complete all of the main and side content. Marvel’s Spider-Man 2 is the same length as the first game in the series, Marvel’s Spider-Man. However, it is longer than Marvel’s Spider-Man: Miles Morales.
This has been confirmed by Insomniac Games’ Senior Game Director, Ryan Smith, in an interview with VG247. In that interview, Smith explained that Marvel’s Spider-Man 2 would be “in the same ball-park as the first game in terms of overall playtime” and that they weren’t looking to make it an epic “80-100 hour game.”
While fans looking for a lengthy Spider-Man adventure may be disappointed, there will still be plenty of collectibles and things to do outside of the main story. You’ll also have a much larger open world to explore, with even more districts than the previous 2 Marvel’s Spider-Man games.
