Cloudspire is strategy game for up to 4 players heavily influenced by both tower defense and MOBA (Multiplayer Online Battle Arena) games. Solo and Cooperative play is driven by a scenario book that chronicles the story of the game from the perspective of each individual faction. Players will control one of four unique factions in a battle to destroy and steal source energy from their opponents. Send and defend against armies and minions, construct towers to protect your base, and explore with your heroes in search of resources and powerful Relics to turn the tide of battle.

Taking place in the floating realm of Ankar, Cloudspire tells the story of a war to obtain a powerful and rare energy known only as "the source." Each race has their own unique units and heroes as well as the ability to bid and draft mercenaries for hire.

Armies are placed either individually or in stacks to hide powerful units until the last possible moments. Heroes, in the meantime are controlled individually and can join the tide of battle or choose to explore points of interest in search of numerous resources. Meanwhile, the event deck regularly changes the terms of the fight, making each wave exciting and unpredictable.

As armies and minions near opposing bases, they'll need to contend with Spires - powerful defense towers that can be built around the board. Fight for control of build sites and obtain new spire schematics to build an impenetrable defense and hold off the enemy. Upgrade your home base to unlock new abilities and strategies. Level up your heroes and lead your armies into combat with advanced and upgraded skills!
