This game is inspired by Plant vs zombie.
A brief History:
A God-Demon stone was formed a million years ago. It held tremendous power that could be said that whoever got the stone rule the whole universe. As a matter of fact, many evil, devil or demon alike rushes for the stone, of course for power to be the strongest. Meanwhile, gods also have plans to obtain and would like to control the power no matter of expense of killing each other. It is worth it because if the demon got the stone, the Universe will no long in peace, so they do whatever it take to claim the stone. God assassinate god, demon absorb other demon, demon kill god and god kill demon. The God-Demon stone get stronger and stronger by absorb those die soul and trap into the stone making it impossible to possess by both party. Finally, a very powerful demon god who is half demon and half god use all of his power to break the stone into seven pieces spread all over many planet in the Universe.
The player is a king of an empire who leads his armies to the fallen area of a God-Demon stone. It is not a peaceful journey but full of danger that many animals become abnormal and start to kill people and villager. Player has to build many strong towers to make sure that evil monster will not be able to pass through.
The overall game is kind of like plant vs zombie. All the enemy will come from the right and try to reach to the left to destroy player’s hero altar and play will be lose the game. However, there will be a boss fighting stage. The boss will not try to reach the hero altar, but will walk around and destroy any available towers. If no more towers then it will go to the hero altar. After a boss fight, player will receive a magical stone that a rumor said it is a small piece from the God-demon stone. Player can equip the stone to any tower to boost its power according to its element like fire, water, ice and more. For example, if a fire magical stone is equipped into a fire base element tower, it will triple the tower’s power, but if it is put into an opposite element like water tower, it will increase the tower very little, and for some other towers will just double its power. After equip the stone, the tower will increase soul when killing a monster and that soul can be used to modify the tower to ever stronger. After the battle, the stone is unequipped from the tower automatic, and a new battle will from the original tower and equip the stone and getting soul and modify tower all over again. The tower can face any direction when placing it for the first time. After that the direction it’s facing is fixed. Some tower can fire in multiple directions. Player can go to the research center and use upgrade stone to upgrade a tower such its fire rate, defense, and damage. A new tower can be obtained through chip pieces dropped from monster. Player then match the piece together to get a new tower. If the matched piece is an old tower, player will receive an upgrade stone instead. Every tower will have its own unique element. The grid will randomly generate a random element. If an element tower places on an opposite element of the grid, the tower will be weakening. On the contrary, if it is placed on the same element, its power will be double.
