Rovio and SEGA today announced a limited-time crossover with the Godzilla franchise in Sonic Rumble starting 22 Dec 2025 through late January 2026.
Why it matters: It's one of Rumble's biggest themed updates, and an unexpected announcement for the party mobile game.
What's new: The event introduces a new stage, unlockable characters, and exclusive abilities.
Official details follow...
New Stage: Godzilla Survival
Survive Godzilla’s rampage on up to three boats in the middle of the ocean!
- Avoid Godzilla’s devastating Heat Ray and the lurking Shockirus.
- This isn’t just some cruise, it’s an intense, high-stakes battle at sea. You only have one chance to respawn, so run fast to dash and dodge the destruction.

Unlockable Kaiju & Skills
A roster of legendary monsters is available to collect and play, allowing you to unleash your inner Kaiju and dominate the chaos!
- Free Pass: Unlock Godzilla with the devastating Heat Ray, and buddy Fire Rodan for free.
- Premium Pass: Get another skill for Godzilla, Nuclear Pulse, and unlock King Ghidorah and his Gravity Beams. Mothra joins as buddy, too!
- RSR Shop: Look for Mechagodzilla and the chilling Absolute Zero blast, and Destoroyah with the Variable Slicer.
