You lead a small rat outpost seeking safety from predators and monstrous enemies. Build it into a settlement and protect its citizens as hostile waves attack.
Use cards in real time to manage the economy, construct buildings, recruit military units, and deploy skills. Place defenses and direct your troops while balancing the needs of the city with its protection.
Each run starts with a basic deck that you can refine by adding, removing, and upgrading cards. Choose among leaders with different traits, respond to random events, and unlock more cards for future attempts; a city’s fall ends its campaign.
Players who enjoy Ratropolis often praise its unusual blend of card-based city management and wave defense, along with the different strategies offered by leaders and cards. Cute rat characters and the appeal of unlocking options and trying another run also come up. Some players find the real-time pace hectic, the difficulty and card draws frustrating, or the runs repetitive, so these strengths do not land for everyone.
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!
