RGG’s Project Century is an action game called Stranger Than Heaven

Sega and Ryu Ga Gotoku Studios revealed more details about their previously teased historical title, which was first revealed at last year’s Game Awards and codenamed Project Century. In a trailer shown at Summer Game Fest 2025, RGG revealed that the game is called Stranger Than Heaven. The title reveal trailer did not reveal any details about the game’s release date or platforms, but it did show a glimpse of its action gameplay.

The game’s protagonist, who gives his name as Mako Daito, appears to be some sort of agent of subterfuge. He implies he may not be Japanese and has striking blue eyes that feature prominently in the character art. The trailer’s description also doesn’t reveal any details except that it offers “another glimpse into the game’s world.”
