Ratocalypse is a turn-based strategy game in which players lead an expedition by designing the behavior AI of their rat soldiers. Combat plays out automatically in turn-based rounds. Players watch their soldiers fight according to the strategies they built and adjust tactics when needed. The demo covers roughly three hours of the game's opening.
A soldier’s AI design offers more than 80 conditions for deciding when each skill is used, along with fine control over skill order and preferred movement positions. At the settlement of Rataponia, players can also build and upgrade more than 10 facilities while recruiting and training their soldiers.
SeonWoong Lee, lead producer of Ratocalypse, said: “In turn-based combat games, players usually issue a command at every moment. Instead, we wanted to offer a different kind of strategic fun: designing behavior conditions and priorities so that characters make the best decision on their own in any situation. Please give the demo a try and share your feedback. With you, we’ll shape it into an even better game.”
The Ratocalypse demo is available to play for free on PC (Steam) starting October 13. The game is targeting an Early Access release in 2027, and more details and development diaries can be found on the Cassel Games website.
