Call of Duty: Mobile’s Season Four: Eternal Prison is not trying to be subtle. The update, which rolls out on April 22nd, slaps a classic multiplayer map onto DMZ: Recon and Battle Royale, then parks two very angry kaiju on top of it. Rebirth Island is back, and it has brought an extraction headache, a high-risk prison, and a crossover that feels like someone left the zoo unlocked. Players who thought their loadouts were ready might want to double-check their body armor... and maybe their life choices.
The headline act is Rebirth Island. This map first appeared way back in the original Black Ops, which means it has enough nostalgia to power a small generator. It sits in the same hall of fame as Rust, another map that has ended countless friendships. Now it arrives in both DMZ: Recon and Battle Royale modes. The Battle Royale version even gets a fresh graphical makeover, so the crumbling walls look a little more cinematic while players sprint through them. The island’s famous prison is not just a decorative landmark this time. It contains a High Danger Zone that dares squads to push inside for better loot. On top of that, a new extraction mechanic means no one simply waltzes out of a match. A boss stands between players and their exit, as if the island itself decided to enforce a very strict curfew.
That is where the tension cranks up. Veterans may remember Rebirth Island as a close-quarters brawl, but DMZ: Recon adds an extra layer of paranoia. The extraction boss fight is the kind of design choice that says, congratulations on surviving, now do it again with more explosions. It is a clever way to make the final minutes of a match feel less like a victory lap and more like a panic sprint through a monster movie.
Speaking of monster movies, Season Four also introduces the official Godzilla x Kong collaboration. Players earn Hollow Earth energy by completing objectives, and once the meter is full, they can enter an exclusive minigame. In that mode, they get to stomp around as Kong, Godzilla, or Shimo. That is right—the game is letting normal humans become building-sized problems. It is hard to say which is more intimidating: an enemy squad on a killstreak or a teammate who suddenly decides to play as Godzilla and treat cover as a suggestion.
To be blunt, this crossover is exactly the kind of chaos Call of Duty: Mobile does well. It does not just add a skin or a sticker. It hands players a kaiju-sized power fantasy and shoves them into a minigame where subtlety is dead and collateral damage is basically the point. For anyone who has ever wanted to settle a match by stepping on it, this is the update.
Beyond the giant footprints, Season Four includes a handful of other events. There is a Mother’s Day-themed shooting event, which sounds like an odd gift but is certainly more exciting than a bouquet. There is also an event centered on Rebirth Island itself, giving players another reason to explore the map’s new tricks. The Battle Pass follows the theme with items that fit both the island setting and the kaiju guest stars. That means players can collect gear that looks ready for either a tactical extraction or a rooftop fight with a giant lizard.
Here is a quick look at what the update throws into the mix:
| Content | Details |
|---|---|
| Rebirth Island | Available in DMZ: Recon and Battle Royale |
| High Danger Zone | Risky prison area with better rewards |
| Extraction Boss | New boss fight before players can leave a match |
| Godzilla x Kong Minigame | Play as Kong, Godzilla, or Shimo |
| Hollow Earth Energy | Earn energy to access the exclusive minigame |
| Mother’s Day Event | Shooting-focused seasonal activity |
| Battle Pass | Themed items for island and kaiju content |
For players who want a head start, checking the current in-game code list is still a smart move. Free rewards are free rewards, even when a giant ape is breathing down the player’s neck. And if the trigger finger still itches after all of this, there is no shortage of other shooters on iOS worth reloading for. But honestly, Season Four makes a strong case for staying right where the kaiju are.
