In a recent interview with Comicbook, Senior Brand Director at Crystal Dynamics Rich Briggs has revealed that the campaign in Marvel's Avengers can be either 10 to 12 hours long, or a whopping 30 hours; depending on how deep players want to go into it.
"I think it'll depend on exactly how deep you want to go into it. So if you think about previous Crystal games, you know that if you want to be playing your way through the core story, it's going to be in that area, 10 to 12 hours," revealed Briggs while also adding that the game's lenght could be compared to that in the new Tomb Raider games.
"But if you want to see everything there is, and do all the side missions and everything else, you're generally looking at 30 plus hours in the Tomb Raider games. So we're not putting exact numbers on it just yet, but you can expect something comparable to what we've done in the past with that regard. And then, of course, you have the extended narrative and the extended game plan, more heroes post-launch.”
