Today Sony announced that PlayStation 4 multiplayer gaming fans are invited to join in their free PS4 multiplayer week starting February 17th and running through February 23rd without any PS Plus membership required. 
Here are the details from James Hallahan of PlayStation Plus, to quote:
"We’re back with another free multiplayer weekend on PS4, but this time, the PS Plus team is extending it a full week. That’s right — one full week of competitive or cooperative play online! This should give you enough time to prestige at least once on Call of Duty: Infinite Warfare, right?
Starting this Friday, February 17, you, your friends, your next door neighbor — everyone — will be able to access the online multiplayer modes in any PS4 game that you own without a PlayStation Plus subscription.
Free online multiplayer access begins February 17 at 12:01 AM Pacific and runs to Sunday, February 23 at 11:59 PM Pacific. Hop on to PSN during the free week with your favorite multiplayer game — no membership commitment is required during this period. Enjoy!"
