Evaluation

Ratropolis launched in Early Access in November 2019 and reached its full 1.0 release on December 22, 2020. During and after Early Access, Cassel Games shipped a steady stream of feature updates — adding new leader modes, cards, advisors, and gameplay systems. The most substantial post-launch content update came on December 21, 2022, adding 6 new leader abilities and 12 new advisors. After December 2022, the studio went quiet for over two years. When they next posted on April 7, 2025, it was to promote their new game Ratopia — a successor title set in the same world. In that post, the developer acknowledged the silence, noted they were focused on Ratopia's development, and said bug fixes for Ratropolis would be addressed "once Ratopia has stabilized." This framing is consistent with maintenance-mode support rather than new content development — no new cards, leaders, or expansions were announced for Ratropolis. The only DLC listed is the Ratropolis Soundtrack, which released in April 2020. There are no unreleased DLC items on the store, no roadmap for future content, and no developer statement indicating new gameplay content is planned. The April 2025 post references only bug fixes, not content additions. With the studio's attention clearly shifted to Ratopia, a two-and-a-half year gap since the last meaningful content update, and no announced plans for future Ratropolis content, the game is best understood as a complete, finished product. The December 21, 2022 update represents the last substantive content the developer added to the game.

About this game

Ratropolis combines roguelite, deck building, and tower defense with real time strategy gameplay. Lead your small rat outpost to safety and defend your rat citizens from predators and monstrous creatures. Build the largest 'Ratropolis!' and etch your name into rat history!

Choose from over 500 cards of economy, building, military, and skill types to execute your strategic command. All leaders begin their journey with a deck of 8 basic cards. Building an efficient deck is key for protecting your rats from waves of rat-thirsty enemies. Add, remove and upgrade your cards to create a deck worthy of a true leader!

Defending your rats in the city will be a challenge. Get aid from advisers with talents in finance, defense, or leadership. They will provide you with better options when chaos arises. When the city falls your campaign will end, but with every end a new beginning is born. Unlock new cards to expand your options and make each defense a new experience.

Now lead Ratropolis to victory and save your Ratizens from destruction!
