Online multiplayer gaming on PlayStation 4 will require a PlayStation Plus subscription, said Sony in a video advertising the console's simple secondhand game process.
Sony also mentioned it in a slide during its E3 press conference.
The fine print in the video above notes, "PS4 multiplayer online access requires PSN account & PS Plus subscription."
A PlayStation Plus subscription costs $17.99 for three months or $49.99 for a full year; Sony will also be offering a new one-month subscription for $9.99. Existing subscribers on PlayStation 3 and PlayStation Vita will have their memberships extended to PS4, including one free PS4 game per month from the Instant Game Collection.
Xbox Live Gold, which is required for online multiplayer gaming on Xbox 360 and Xbox One, costs $24.99 for three months and $59.99 for 12 months.
