Battle to Victory(Lite)

Can you help me with an exciting description of a tower defense game? The game has many mobs, and the player has a base with the objective of protecting the gate. Players can generate silver coins by purchasing silver mines with gold coins, and use these resources to deploy various types of defensive facilities such as machine gun towers, ice towers, magic towers, and support towers. When mobs attack, these towers can eliminate them and collect the resources dropped by the mobs.
