Boss Fighters QR is a co-operative fantasy campaign game where players battle against ten unique boss monsters that react tactically to their actions. This hybrid game combines elements of a classic card game with a digital application to create a seamless interplay of strategic deck building and dynamic boss battles. The Scan & Play mechanic of Boss Fighters QR allows the game to instantly recognize player cards as they are scanned, which then triggers challenging responses to the players’ choices, in real time.

At the start of the campaign, each player chooses a hero deck—Jungle Troll, Hill Halfling, Copper Dwarf or Forest Elf—and combines it with one of the four available classes: Warrior, Mage, Rogue or Druid. Every boss has its own unique tactics and abilities, strengths and weaknesses, which the group of heroes must first deduce and understand before they can effectively fight it. Upon successfully defeating a boss, players gain loot cards hidden in three secret loot boxes, which they can use to improve their decks and unlock new, powerful abilities. Each boss battle can be attempted at one of four levels of difficulty, making it easy to customize the challenges of Boss Fighters QR for new players with little gaming experience, or to provide an epic encounter for expert players.
