What are keyshops?About Doomstacker
Sometimes you want tactical depth. Sometimes you just want a gigantic army that steamrolls everything in its path. Doomstacker combines both - a condensed fantasy-strategy experience in an auto-battler format, where smart planning and absurdly huge stacks go hand in hand.
Build your castle
Develop your castle and decide which creatures you want to rely on. But the higher the difficulty and the tougher the opponents, the more you’ll adapt to whatever resources you have the most of - and to the artifacts you manage to find.
Create synergies
Each castle has 10 creatures, but you can bring only 5. Some lineups work far better than others, and there are tons of possible combinations. Experiment and discover your favorites.
Grow into unstoppable armies
In Doomstacker, any creature can become terrifying - if you have thousands of them. And there are multiple ways to boost your army even further.
Upgrade and evolve into a Doomstack
If your resources allow it, you can upgrade creature buildings multiple times. A big stack can become something much, much worse for your enemies… a true Doomstack.
Artifacts and rings
Strengthen your armies by buying and upgrading artifacts - making them stronger, tougher, and faster. Equip rings to grant an army an ability that originally belonged to a different one, opening up even more build possibilities. The number of combinations is huge. Try weird ideas. Break the game (legally).
Play for fun or play seriously
We want you to enjoy both:
pure power fantasy - build an enormous army and revel in your own might
competitive play - climb rating, learn matchups, and squeeze value from every attack and ability
Study battles your way
It’s an auto-battler, but battles play out in turn-based mode. Use the battle log to rewind to any previous turn and replay from that moment - step-by-step (like classic strategies) or in a faster automated view (like auto-battlers).
Fight AI or player army “ghosts”
Battle AI armies or face copies of other players’ armies at a similar rating. There’s no rush - prepare for each fight at your own pace.
Build the Doomstack of your dreams!
