Activision has announced an eye-catching free trial of Call of Duty: Black Ops 6 that just so happens to clash with the launch week of rival first-person shooter Battlefield 6.The week-long free trial of Black Ops 6, which includes full access to the campaign for the first time ever, as well as all of Multiplayer (excluding Ranked Play) and Zombies, kicks off at 9am PT on October 9 — just a day before Battlefield 6’s October 10 release date — and ends 10am PT on October 16.The Black Ops 6 trial even includes new content from The Haunting update, like the Gravity, Rig, and Mothball Multiplayer maps, Haunted Havoc Zombies limited-time mode, and more.While Activision hasn’t come out and said this trial is a direct attack on EA’s Battlefield 6 launch, fans are under no illusion about the optics here. It’s worth noting that Black Ops 6 is already playable via Xbox Game Pass Ultimate and PC Game Pass, but the trial will benefit Essential and Premium users on Xbox and of course players on PlayStation and Steam.It’s the latest salvo in what has become a popcorn-worthy back-and-forth between Activision and EA, with each mega publisher’s big budget FPS vying for the hearts and minds of the gaming community this holiday season.In August, Activision shocked the Call of Duty community when it confirmed that Operators, Operator Skins, and Weapons from Black Ops 6 would no longer carry forward into Black Ops 7. This came as a big surprise to players who had expected content they’d bought for Black Ops 6 to carry forward, as it has done with previous entries. Explaining the decision, Activision said Black Ops 7 “needs to feel authentic to Call of Duty and its setting.”The feeling was that Activision felt the heat from Battlefield 6, which is going for a more grounded aesthetic. Developer DICE has indicated it has no plans to release crossover skins that would break the aesthetic Battlefield 6 is going for, and promised the developers were listening to fan feedback.In a recent interview with DBLTAP, Battlefield 6 design director Shashank Uchil doubled down on EA's commitment to grounded realism, and even pointed to Call of Duty's infamous Nicki Minaj skin as something Battlefield 6 doesn't need.“It has to be grounded," he said. "That is what BF3 and BF4 was — it was all soldiers, on the ground. It’s going to be like this,” Uchil said, pointing at the key art featuring soldiers in soldier gear looking out over a wartorn New York City.He added: “I don’t think it needs Nicki Minaj. Let’s keep it real, keep it grounded.”Then, last month, EA ramped up its Battlefield 6 marketing, taking a direct jab at Call of Duty with a new live-action trailer. More recently, Activision extended the Black Ops 7 open beta to run an additional 24 hours to October 9, taking it right up to Battlefield 6's release date.Both games are crucial releases for their publishers. Battlefield 6 leads the charge, releasing October 10 before Call of Duty: Black Ops 7 counter-attacks on November 14. It will be interesting to see which of the two mega publishers is happiest when the dust settles.Wesley is Director, News at IGN. Find him on Twitter at @wyp100.
