The Call of Duty: Modern Warfare 4 beta has officially launched, and players are already grinding to unlock rewards before the test window closes. The early access phase, available on PS5, Xbox Series X and S, and PC, will end on August 25 at 10 a.m. Pacific, 1 p.m. Eastern, 6 p.m. UK, and 7 p.m. European time. That gives players a limited window to rack up kills and earn exclusive beta rewards before the servers go dark for the weekend.
But the action doesn't stop there. The following weekend, the beta opens to all players across all platforms, including the newly announced Nintendo Switch 2. This open beta will run without any restrictions, meaning anyone can jump in and experience the game before its full release. The staggered rollout is a familiar pattern for the franchise, giving early adopters a head start while building hype for the wider player base.
The beta offers a first taste of the game's single-player campaign, which plunges players into a full-scale North Korean invasion of the Korean Peninsula. A young squad of South Korean soldiers fights to survive on collapsing front lines, while a vengeful Captain Price wages a personal war from the shadows, staying one step ahead of those hunting him. As Price's off-book mission collides with the forces behind the invasion, the conflict spirals beyond anyone's control, pushing the series into darker and more dangerous territory.
For those looking to maximize their beta time, the early access period is the only chance to earn exclusive rewards tied to this phase. Players should prioritize completing matches and challenges before the August 25 cutoff. The open beta next weekend will offer a more relaxed environment, but the early access rewards won't be available again.
Modern Warfare 4 promises to bring long-running storylines to a powerful and emotional breaking point, with consequence and escalation at the forefront. The beta is the first opportunity for fans to see how the developers have evolved the gameplay and narrative since the last installment. With the clock ticking on early access, players are advised to make the most of the remaining time.
