The original press release for Need for Speed Rivals made no mention of a PC version; however, the PR has since been amended revealing the PC version will arrive on November 19 alongside the Xbox 360 and PS3 versions of the game. Xbox One and PS4 versions will launch "later this year."
Other than differences in graphical fidelity and online player count, Rivals features differences in its new marquee feature "AllDrive" across current- and next-gen systems. AllDrive is the ability for the game to "seamlessly" adapt to player interaction as they cross paths in the open-world space. On next-gen consoles, players will have unspecified exclusive ways to interact with the game using other devices.
Nilsson would not detail if the PC version's feature-set would be based on the current- or next-gen platform versions.
Expanding on how AllDrive would work, Nilsson offered an example of how the game would react to friends in the same world engaged in separate chases that come across each other. With the new feature, Need for Speed Rivals would recognize player proximity and any current missions and automatically shift objectives and scoring to that of a traditional co-op encounter. Players can enter and exit each other's worlds to race and interact "on-the-fly." The core features of AllDrive will be available on all platforms.
