Gather crystals, build your army, attack enemy castles, and defend your own.
Every crystal brings your next move closer. Gather resources, raise an army, and protect your castle in Crystal Frontier:Attack&Defend, a colorful strategy game where building, attacking, and defending share the same battlefield. GATHER TO GROW Guide your crystal collector through the field and bring your haul back to the processing station. Turn bright blue crystals into resources for your next building or upgrade. CHOOSE YOUR FORCES Build barracks and choose units such as human warriors, elven archers, and human mages. Watch your troops join the battlefield as you decide where to invest next. ATTACK AND DEFEND Your army advances toward an enemy castle while incoming forces threaten your own. Keep gathering, develop your base, and balance military growth with castle defense. BUILD YOUR STRONGHOLD Add barracks, strengthen defensive towers, and upgrade your castle. Each investment changes what your base can send out or withstand. Scout the battlefield to see how the fighting is unfolding. A BRIGHT FANTASY BATTLEFIELD Explore a playful 3D world of sparkling crystals, blue-roofed castles, and expressive fantasy troops. Simple movement keeps you close to the action, while resource choices give you something to think about with every trip. Collect your next haul. Build your next force. Keep your castle standing.
