In one of the most surprising discoveries in recent memory, an unreleased 1992 Sonic arcade game called SEGASonic Bros. has been revealed by Tumblr user ShouTime.
The game appears to be a puzzle game that was location tested but sadly failed said test. ShouTime, the user responsible for discovering the game’s arcade board, is also the person responsible for the ROM dump of the SEGASonic Popcorn Shop that was made available back in October 2015.
Another image of the game and some further information was also released by ShouTime. This information confirms that the game was developed by Bubble Bobble creator Fukio Mitsuji and the second screenshot shows a menu screen that bares surprising similarities to Puzzle Bobble:
SEGAbits have also discovered mention of the game from an old issue of EGM. The article details a few announcements regarding various Sonic games, including a comment that mentions an upcoming arcade game that, “invites multiple players to assume the role of different colored Sonics”.
Furthermore, a Sonic Retro forum user called Black Squirrel has also discovered mention of another unreleased Sonic arcade game in a different issue of EGM. The extract says, “We have developed two Sonic arcade games that have never been released because they were not the specialness that Sonic was”.
Fingers crossed ShouTime reveals further information about the game in due course!
