Mega Crit shifted away from Unity (used to develop the first game) after the latter announced a controversial install-fee policy.

Mega Crit surprised many fans when it announced Slay the Spire 2, a sequel to its popular rogue-like deck-builder. Launching next year for PC via Steam Early Access, it features new and returning classes, enemies, bosses and more. However, it’s also developed on a new engine, with the developer confirming to IGN that it ditched Unity in favor of the open-source Godot engine.

While it allows for “modern features, all-new visuals, and expanding moddability,” Mega Crit previously criticized Unity’s controversial install-fee measures. Despite the “immense amount of time and effort” the team had spent on its new title, it threatened to shift to a new engine unless the “changes are completely reverted, and TOS protections are put in place.”

Unity eventually backtracked, with CEO John Riccitiello resigning, but it seems Mega Crit moved to a new engine anyway. Of course, the title is Slay the Spire 2, and the rest is history.

How the sequel will leverage Godot to expand its modding capabilities remains to be seen, but it also promised “new ways to play”, which “aren’t yet announced.” Stay tuned for more updates, especially in the coming year when more details about early access are revealed.
