Monkey Ball, Altered Beast Join Sonic Rumble Event

Sonic Rumble is gearing up for a special pre-launch crossover event before its global release. Surprisingly, this collaboration features iconic Sega characters from classic franchises rather than third-party IPs, bringing together gaming legends across generations.

Limited-Time Character Unlocks

The event runs from today through May 7th (one day before global launch), offering exclusive rewards for players in soft-launch regions. All participants can claim the Werewolf character from Altered Beast at no cost. Sega Star Event Pass subscribers gain access to two additional characters: the Weredragon (also from Altered Beast) and Opa-Opa, the original Sega mascot from Fantasy Zone.

Premium and Shop-Exclusive Characters

The in-game Ring Shop will feature Upa-Upa and Werebear, while the premium Red Star Ring Shop offers Super Monkey Ball favorites AiAi and MeeMee. This unusual pre-release event signals Sega's ambitious content roadmap - the company confirms this crossover marks just the beginning of planned collaborations throughout Sonic Rumble's lifecycle.

Meanwhile, Supercell prepares another mobile gaming innovation. Our Mo.co preview details why this eccentric monster-hunting sim deserves attention ahead of its iOS/Android launch.
