Atmospheric battles in 3 Minute Heroes take place in the form of deck-building skirmishes, where you need to work out a strategy before starting the battle. The player will defend the castle, form a card deck with abilities and fight off the attacks of enemies attacking the protagonist’s house. Each level takes three minutes, during which there are waves of opponents who want to destroy the hero’s property. The main task in 3 Minute Heroes is to create a strong defense with the help of units and special cards that open up strong defensive or offensive skills and can affect the outcome of the battle.
