It's that time of year again: The next Call of Duty is on deck, and Activision's got the beta dates to prove it. Modern Warfare 4 won't hit the streets until late October, but the multiplayer beta begins a full two months ahead of time.As usual, Activision is holding two beta weekends: One for those who pre-order the game and one for everyone else.Weekend 1 (August 21-25): For those who pre-order Modern Warfare 4 on PC, PS5, or Xbox (no Switch 2 beta)Weekend 2 (August 28 to September 1): A proper public beta on all platforms (including Switch 2)Fairly expected for a CoD beta calendar, except for a few abnormal details, like how Switch 2 players will be left out of that first weekend (that version might be coming in a little hot compared to the others). There's also the fact that pre-order weekend is five days instead of four—further stretching the definition of "weekend." That means pre-order players can start the same day as the Call of Duty Next livestream and won't have to watch streamers enjoy a 24-hour headstart.Less surprising, but surely disappointing for many, is that Game Pass subscribers will not be entitled to early beta access this year. They were for both Black Ops 6 and 7, but apparently Microsoft's decision to exclude new CoDs from its service also extends to betas.

Players can unlock "19 different weapons before deploying into everything from small-scale 3v3 skirmishes to massive tactical battles featuring tanks and more," a blog post published today reads. "Test your mettle across new and returning modes, from Search & Destroy to the brand-new Kill Block, plus the Training Mobility Course."Kill Block is a modular multiplayer map made for both small and medium-sized modes. The map is divided into chunks that dynamically swap between rounds. It's the sort of experimental gimmick that seems unlikely to catch on in a big way, but 10v10 Gunfight on Kill Block was a highlight when I played Modern Warfare 4 back in May. During one round, the map became a 1:1 recreation of Crash from the original 2007 Modern Warfare—charming. 2026 games: All the upcoming gamesBest PC games: Our all-time favoritesFree PC games: Freebie festBest FPS games: Finest gunplayBest RPGs: Grand adventuresBest co-op games: Better together
