Call of Duty: Mobile Season 4, Eternal Prison launches April 22 with Godzilla x Kong crossover

Call of Duty: Mobile is setting Season 4 up as a crowded launch day, with Eternal Prison going live on Wednesday, April 22, 2026, at 5 PM PT and packing in the kind of headline additions that change daily play fast. The official trailer flags a new Mythic Weapon, DMZ: Recon Boss, a new map, and more, giving mobile players a clear reason to log in the moment the season flips.

The biggest share hook is the crossover itself. Call of Duty: Mobile has tied Season 4: Eternal Prison to a Godzilla x Kong collaboration, and the official channel’s teaser clips and logo posts have reinforced the message that the Titans are coming. That puts one of the game’s biggest pop-culture crossovers squarely inside the season rollout, with Activision Publishing, Inc. leaning into a Monsterverse-style event rather than treating the collaboration as a side note.

The timing matters, too, because the rollout may not be identical everywhere. A Garena Call of Duty Mobile post points to April 23 for some regions, so players outside the main global schedule may see Eternal Prison a day later. That regional split is worth watching if your squad is planning around reset timing, ranked pushes, or the first wave of season challenges.

The trailer has also sparked one more talking point: creator videos circulating online suggest the new Mythic weapon could be the DP-27. That detail is not confirmed in the official trailer description, but it has already become part of the early-season conversation as players try to guess how the new weapon tier will fit into the meta. For now, the confirmed takeaway is simpler and bigger: a fresh Mythic, a new boss encounter in DMZ: Recon Boss, a new map, and a Godzilla x Kong crossover are all lined up for the same launch window.

For mobile regulars, Eternal Prison looks built around immediate impact rather than a slow drip of features. The launch lands with a fixed time, a named season, a crossover event, and mode changes that should affect what players queue for on day one. With April 22 locked in at 5 PM PT, the countdown is already on.
