Vortex Vi.Rus mainframe is the next event inModern Warfare 3andWarzone. Here is everything we know about the upcoming new challenges, including reward predictions.
MW3andWarzoneSeason 3 is well underway. The devs have already treated fans to aGozilla x Kongcrossover event andHigh Tripto celebrate 4/20. We still have some time before the mid-season update goes live, so Vortex: Virus Mainframe will help bridge that gap.
MW3 & Warzone Vortex: Virus Mainframe event start date
Vortex Virus Mainframe begins onWednesday, July 23, 2025, at9 AM PT / 12 PM ET / 5 PM BST
If players haven’t unlocked all of the free rewards for Blaze Up, you only have a few days left, as the event also ends on this date. And for everyone who has enjoyed the High Trip Resurgencegame mode, that mode will also be removed once Vortex Virus Mainframe starts.
It hasn’t been confirmed how long the latest Vortex event will last, but given that the Season 3 mid-season update is scheduled to start on May 1, Vortex Virus Mainframe will most likely be around for one week.
MW3 & Warzone Vortex: Virus Mainframe reward predictions
Like other events in the past, Vortex: Virus Mainframe rewards are earned by accumulating XP. The fastest way to earn XP is through using double XP tokens, playingWarzone, or jumping into small-map playlists in multiplayer that are relatively easy to get kills in. And, if you want to speed up the grind, a bonus 1000 XP will also be awarded for each match completed with the Bacillus skin equipped, which can only be obtained by purchasing the Vi.Rus Ultra Skin Tracer Pack.
Activision has yet to reveal the official rewards, but we expect it to resemble previous challenges. With that in mind, here is the likely list of prizes.
