Heroes of Might and Magic: Olden Era adds a roguelike mode, Thieves Guild, and a full underworld

Unfrozen has laid out the early access roadmap — their word, not ours — for Heroes of Might and Magic: Olden Era, and it includes a roguelike mode, a Thieves Guild built around surveillance and espionage, and a sprawling underworld layer stretching beneath every mountain and valley on the map.

The underworld comes with its own unique terrain and connects to the surface across the entire map. The Thieves Guild adds intelligence-gathering mechanics to keep tabs on opponents. Unfrozen is also breeding new monsters, with lich dragons name-dropped as an example of the more powerful creatures on the way.

Olden Era is still in early access, and Unfrozen is actively expanding the game. The roguelike mode looks to offer a self-contained, replayable experience alongside the core strategy campaign — a smart way to broaden the audience without touching the classic formula.
