On Monday, the first beta weekend for Call of Duty: Modern Warfare officially ended, but players won't have to wait long to jump back in, as a second trial will be available this coming weekend from September 19 (for those who pre-ordered) through September 23. If you haven't, then you'll have to wait until the beta opens up to everyone on September 21. \n \nIn a message thanking fans for playing the first beta trial for Call of Duty: Modern Warfare, it was confirmed that this coming weekend's beta period will feature a 32v32 Ground War mode. \n“Thank you for playing the Call of Duty: Modern Warfare beta! We hope you’re enjoying everything we’ve shown you so far, but we aren’t done yet! On Saturday, September 21, during weekend two of the beta, we’ll be taking your multiplayer experience to the next level. Taking place on a new map, Karst River Quarry, you’ll get your hands on 32v32 warfare in a new mode, Ground War.” \nOf course, we already know that the game, which is currently scheduled to be released on October 25, will feature a 50v50 Ground War mode, which, along with the Blackout mode in Black Ops 4, will be the largest game mode in franchise history. It's also likely that the game will, at some point, get a Battle Royale mode added. But, as of right now, a 100-player free-for-all mode hasn't officially been announced by Infinity Ward. \n \nOn Monday, a trailer for the second beta trial for Call of Duty: Modern Warfare was released, and you can check it out below. \n \nhttps:\/\/youtu.be\/er0GY9dzzwk \n \nOn Tuesday, Activision revealed the crossplay details for Modern Warfare, one of which includes the ability to opt-out of playing with or against users on other platforms. But, if you opt-in, which most players probably will, you'll have the ability to play with and against your friends on all three of the supported platforms (PlayStation 4, Xbox One, and PC.) \n \nTo enable crossplay for Call of Duty: Modern Warfare, all you have to do is sign up for a CoD account. On top of that, the following information regarding the function was provided. \n \n \tYou can decide to use a mouse and keyboard on PlayStation 4. \n \tXbox One, PlayStation 4, and PC users can play against each other, provided everyone uses controllers, or everyone utilizes a mouse and keyboard. \n \tUsers will be able to go into a lobby where there are no control scheme filters, which will allow players using a controller to play with and against mouse and keyboard users and vice versa. \n \nAll multiplayer modes in Call of Duty: Modern Warfare will support crossplay, and so will this weekend's beta period. If you're looking to try this weekend's beta, then it's available to be pre-loaded onto your console or PC right now. If you already installed last weekend's beta, then all you have to do is update the application.
