GTA: Fortress Monster Tower 4
Evil monster are attacking and now they want to get rid of the good monsters, so they are able to rule the world. They know that the good monsters would want to stop their plans to rule the world and that is something that they cannot tolerate. The idea here is to stop the evil monsters from advancing. You need to set up several huts in order to build an army or just blast them. Let the vault accumulate some gold for you to collect later. You can use the money later to buy more monsters. Remember that monster die afterwards, so you need to add more monsters to the battlefield.
