The major difference between the current- and next-gen versions of Rivals, according to Nilsson, is one of developer philosophy. "It's a mindset of how you think about how people will play these games. To me, visuals are great absolutely but unless you can use that power to play that game differently, then we failed." To ensure success under this philosophy, Ghost and Criterion are "pushing" a feature called AllDrive, which allows friends to enter and exit each other's worlds seamlessly and "on-the-fly."
"AllDrive is fundamentally a way for us to destroy the line between playing alone and playing with friends. Destroying the line between single-player and multiplayer," Nilsson said, before offering a use case scenario for the system. "Imagine you're playing Rivals, you're driving your car as a cop chasing someone. You're going through your progression, collecting points and then I join and we're friends, so we'll be put in the same world." Though the world is "pretty big" and each player can complete single-player tasks, they exist within the same environment and the "two experiences can merge."
If each player enters separate pursuits at different points in the world and eventually come across each other on the same road, Rivals transitions into a co-op state. "The game recognizes that now we're playing together and changes the scoring and changes the objectives for you, to acknowledge that you're now playing co-op," Nilsson adds. Depending on the amount of people you encounter or chose to play with, the game will adjust by providing new variations to play the game. "That to me is really a new mindset and where I think we wouldn't have gone to unless we started thinking along the lines of the next-generation."
AllDrive, however, is not exclusive to Xbox One and PS4. "AllDrive will feature on current-gen and next-gen but there will be differences," Nilsson added, explaining the next-gen's ability to include more online players and "some ways of interacting with that game from different devices." The producer further clarified citing the Xbox One's second-screen SmartGlass app the team's intention to build players "different ways to interact with the game instead of just sitting in front of a TV."
