Bring the thunder and defend your fortress at twice the speed! 

MERGE, BUILD, AND DEFEND
Your fortress is under attack! Choose and place buildings, merge matching ones to make them stronger, and prepare for waves of monsters. Build structures that train knights, horsemen, archers, and mages, while all kinds of turrets and barricades attack or slow down enemies as they approach. Face skeletons, slimes, dragons, giants, and even stronger foes that appear as you progress. Adapt your setup to each threat and prepare for mighty bosses that can quickly break through a weak defense.

MAKE EVERY TILE COUNT
Space is limited, so plan your fortress carefully. Clear trees to open new tiles, decide where to place buildings that train different units, and find the best spots for barricades and turrets. Use every tile wisely, leave enough room to place and merge buildings, and create a layout that balances attack and defense.

Activate permanent x2 Game Speed to face enemy waves twice as fast. Switch x2 Game Speed On or Off at any time and control how quickly the action unfolds.
