UNCHARTED 3′s 3D technique paved the way for split-screen multiplayer support. “There are a number of ways to implement 3D; some are more ‘fake’ than others,” Richmond explained. “We committed to using 3D early on, and we wanted to do it as real as possible because it allowed for splitscreen. 3D and splitscreen are kind of the same thing because the game is basically rendering each frame twice. As soon as we figured out how to do that with 3D, we knew we could handle splitscreen. Now, I am grossly oversimplifying that — the programmers would kill me for saying it was that easy! But basically, our 3D implementation allowed for splitscreen support.” UNCHARTED 3′s splitscreen multiplayer enables dual PSN logins.

“You don’t have to be on some guest account,” Richmond said. “You and your friend can sit down in splitscreen and level up both of your characters. We support two different PSN ID logins.”
