Protect your city by helping command heroes to defeat enemies. Merge useful items or abilities to help your hero out in the heat of battle and slain those enemies.
Players will merge icons on their screen to create items that they will collect and use later on in battle. Players will combat enemies using a turn based system in which the player is allowed to use their items to increase their chances at winning. Items are either attacks to use against the enemies or recovery points. There will be multiple levels with level getting increasingly harder has you go on.
