Sony has announced it's setting one of PlayStation 4's big PSVR exclusive games free this weekend. Firewall Zero Hour will be free for PS Plus members from June 28 through July 1 on PS4. In addition, all players will receive double XP for the duration of the free-play weekend, and your progress will carry over should you decide to purchase the game.

The PS4 game launched in August 2018 to a positive reception. The tactical shooter is multiplayer-based, pitting squads of four against each other. It ordinarily costs US $40 / £25 / AU $40--though it is currently discounted to £16 / AU $25 if you want to own it permanently (in the US, it remains $40). If you're looking to download it, it's a separate entry on PSN from the standard version of the game--you can find it here on the PlayStation Store.

Firewall has also received a number of updates in the past few months, from new missions and rewards to a completely revamped user interface. Two new maps have also been released for free just recently. We said the game "showed that tactical multiplayer FPS games can work on PSVR" in our 2018 VR gaming review.

The free PS Plus games for July 2019 have also been announced. The PS4 games available at no extra cost for PlayStation Plus members next month will be PES 2019 and Horizon Chase Turbo.
