The protagonist in the game, Locke, is an alchemist who has the ability to generate a variety of different objects and defend against the aggression of magical creatures.
This game is very interesting and will give you the mission goal before each battle. It is generally to protect a small town from monster robots. Then give you 2 to 3 minutes to start the fortifications. You can use the wall to surround the protection target group, and then cover a large number of turrets to devastating the enemy's army.
The turret is the main damage output in the battlefield. Then put down the poisonous thunder, frozen thunder, mines in the place where the enemy may pass, and then you can begin to defend the battle.
