About Cards & Cannons
In Cards & Cannons, you build increasingly powerful tower defense realms to churn through unimaginable enemy hordes. Build smart, create choke points and unlock devastating synergies with each more challenging run! - You call the shots. Your deck. Your strategy. Your chaos. How far can you push it?
Gigabrain tactics? Glorious failure? Doesn't matter - run it back!
Discover new cards and make your deck of mighty tower defense buildings even more powerful!
Build increasingly powerful realms run after run, place your defenses and upgrade them to the max! You alone decide how you protect your castle!
You decide where you place the spawners - one wrong move and you will feel it! Lure the enemies into your deadly traps and snatch their shiny loot.
Summon devastating spells and rain destruction on your enemies! No time to go AFK, jump in and help your towers crush the enemy waves!
Stack up powerful abilities, collect game-breaking buffs and discover crazy synergies - from wild lightning storms to... Bananas? Yeah, really!
Battle through different worlds and carve your own path to victory! Each realm brings new enemies, epic duels, and permanent upgrades. Can you become absolutely overpowered and defeat all the bosses?!
