Crystal Fortress

Crystal Fortress is a tactical defense game centered on Phoebe, a warrior, archer, engineer and commander of the Crystal Guard. Lead the defense of the fortress against enemy waves, deploying soldiers, snipers and battlefield turrets while taking the fight to the frontlines. Battles use action points that recover each turn, making it important to weigh attacking against defending and waiting for more points. You control Phoebe directly; allied units act together after her move, followed by the enemy. Between battles, spend gold to improve your units as the defense progresses through chapters and the fortress’s four gates.

Gameplay and features

• Plan around action points: Units recover a limited number of action points per turn. Choose whether to spend them advancing and attacking or defend and wait for recovery, while accounting for enemies doing the same.
• Command Phoebe and the Guard: Control Phoebe directly, then watch allied units act simultaneously before the enemy takes its turn. Summon soldiers and snipers, and place defensive turrets on the battlefield.
• Upgrade units between battles: Spend gold between battles to improve units, including their maximum health, maximum action points, action-point recovery and damage.
• Defend across chapters: Progress through chapter-based stages with different environments as the Crystal Guard shifts its defense among the fortress’s four gates.
