Good news, PS4 owners: if you have a PS Plus membership and live in the US or Europe, you can play Metal Gear Survive for free this weekend. Between now and Monday, June 4, Konami is letting players download a free trial that contains the entire game. You can download the trial here or by searching for Metal Gear Survive in the PlayStation Store on your PS4.

Any progress you make in the trial can be transferred to the full game if you decide to buy it. And to encourage you to take the plunge, Konami is running a 30 percent discount between now and June 8 on the PlayStation Store. That means you can buy it for $28 instead of the usual $40.
