The VR shooter "Firewall: Zero Hour", which is available for PlayStation VR, will be made available for free via the PlayStation Plus subscription in February 2020. There hasn't been a VR title in the PS Plus subscription for a while.
From 4 February 2020, subscribers will also receive "BioShock: The Collection" (including "BioShock", "BioShock 2" and "BioShock Infinite") and "The Sims 4" for the PlayStation 4 in addition to "Firewall: Zero Hour", although these will not include any VR features.
This is how Sony describes "Firewall: Zero Hour": "Become mercenaries and capture - or protect - vital intel in Firewall: Zero Hour, a tactical 4v4 shooter developed exclusively for PSVR. Jump right into these thrilling multiplayer battles with the new season of Firewall Zero Hour - Operation: Black Dawn. The season starts on 4 February and features a new map (Oil Rig) for all players as well as other free content!"
