The Last of Us Part 2 Remastered's developer commentary has revealed that the Seattle map used throughout the game is actually based on the one used in inFamous: Second Son.
Beyond adding in a new roguelite mode, several new unlockable skins, and cut levels that weren't featured in the final version of The Last of Us Part 2, one of the biggest things that The Last of Us Part 2 Remastered adds to the game is developer commentary that goes in-depth for the first time about the creation of the game.
Not only does this let The Last of Us fans see how certain scenes were put together and the intention behind each moment, but it also reveals some previously unheard tidbits about the game's development. One such interesting reveal can be found during Ellie's section of the game in Seattle, Day 1.
Just before Ellie and Dina get to roam around a section of Seattle in one of the game's most open sections, there's a cutscene that plays where Ellie scopes out the area. If you play with the developer commentary on, then game director Neil Druckmann will reveal that the team were actually given an accurate model of Seattle from Sucker Punch, who had created a version of the city for inFamous: Second Son.
Druckmann says that after the team was given the model of Seattle from Sucker Punch, it was then able to map out all of the major story beats that happen to Ellie and Abby while they're both in Seattle, like their visit to the seafront and trek through the city. Of course, The Last of Us Part 2's version of Seattle is very different to inFamous since one is post-apocalyptic and the other is just ruled by a military force, but it's an interesting link between the two developers.
"The first draft we had of all of Seattle is from Sucker Punch games, who made inFamous: Second Son, which takes place in Seattle. So they gave us a 3D model of all of Seattle as a starting point. And then we spent a lot of time mapping out the entire story of where Ellie and Abby go, so we had this very intricate map of all the locations".
It's not clear how much of the original map was kept and used in The Last of Us Part 2, especially since the two have such different takes on the city, but it's an interesting note nonetheless that shows just how closely some of PlayStation's first-party developers work together.
