Breaking from longstanding tradition, the next round of PlayStation Plus freebies began before the new month even arrived. PS4 users can now grab one of June's free games, Call of Duty: WWII. The second freebie, Star Wars Battlefront II, will be free starting June 2, the first Tuesday of the month. This is one of the strongest free games lineups we've seen this year.

Developed by Sledgehammer Games, Call of Duty: WWII released in 2017 and brought the series back to its original World War II-era setting for the first time since World at War in 2008. Call of Duty: WWII is particularly known for having a strong single-player campaign, which clocks in around six hours. The online servers are still live, and while they aren't extremely active, you can expect the player count to tick up since far more people will have access to it on PS4.

In addition to the campaign and traditional multiplayer playlists, WWII also has a fun narrative-focused War mode with unique maps and lengthy attack/defend objectives. The strong package earned the first-person shooter a 9/10 in our Call of Duty: WWII review: "Ultimately, if every shooter set in the European Theater of World War II is measured by how it depicts its D-Day landing--assuming it has such a mission--Call of Duty: WWII emphatically succeeds in its impactful designs and delivery. The sensation of riding the troop carrier as it approached the beach filled me with depression more than dread, knowing I'd survive eventually while many of my surrounding brothers in arms wouldn't. While not equally emotional, this battle's reinterpretation in War mode proves to be a highlight in a superb suite of competitive modes," we wrote.
