Sony has had in the past several free multiplayer weekends on PS4, allowing players to play online without the need of a PlayStation Plus subscription. However, this time around Sony is doing it for a full week and in different time periods for North America and Europe.
The company has announced that starting today and for a full week, online multiplayer will be available for PS4 players for free in North America. Free online multiplayer access began today at 12:01 AM Pacific and runs to Thursday, February 23 at 11:59 PM Pacific.
As for Europe, the free multiplayer event will be slightly shorter, lasting only five days. European players will be able to play for free from 10.00am on 22nd February until 23.59pm on 26th February.
Should you wish to continue playing online after this period is over, you will need to subscribe for PlayStation Plus. In addition to online play, PlayStation Plus also includes other offerings, such as free PlayStation Plus monthly games, exclusive member discounts, online game saves, and more.
