Cassel Games, the indie developer that carved a niche for itself with rodent-centric hits like Ratopia and Ratropolis, is back with a new project.

On the 12th, the studio launched a playtest for their latest title, Ratocalypse, via Steam. It is a turn-based tactical RPG wrapped in dungeon-crawler aesthetics, seasoned with a dash of auto-battler mechanics where you get to tinker with your character's AI.

The premise is quite grim: you play as a prince in a kingdom brought to its knees by a zombie plague, desperately scouring the ruined capital for a glimmer of hope. You will be hacking and slashing through a menagerie of zombie rats—ranging from lowly grunts to undead knights and sorcerers—while commanding a diverse squad of shield-bearers, hunters, elementalists, necromancers, mortar gunners, and outcasts.

You can deploy four characters per battle. Success hinges on how well you synergize your skills and kit your units out with the right runes. Since it leans into the auto-battler genre, you set the tactical behavior for your troops, though the 'squad leader' character allows for more direct, hands-on control.

Ratocalypse includes native Korean language support, and further details, including the release date, will be announced at a later time.
