Zombie Tower Defense

Zombie Tower Defense is a spin-off game of the Plants VS. Zombies game series. It's based on Bloons Tower Defense 6 and unlike the previous games, it is a tower defense game. The objective of the game is simple; stop the zombies from reaching the exit of the track. The plants will attack the zombies as they come in their range, as they are planted near the track. When a zombie reaches the exit (leaks) a number of lives are lost, depending on the HP of the zombie. When the life total reaches zero, you lose. The entities you use to fight the zombies are plants. And there are special kinds of plants called heroes. Only one hero can be placed on the map and they upgrade automatically by XP gained over the rounds. Each track has a difficulty of its own. And there are additional track modifiers which add of remove certain properties. There is also currency, two types; cash, which is used for buying stuff during battle; and gems, which is used for Special Plants, Powers, and other stuff and they are saved overtime. They are mostly earned by completing tracks and daily missions.

Plants
Plants are the main line of defense and your army. Each plant has its own range, when a zombie enters it, the plant executes its attack. All plants are divided into 4 classes; Primary, Military, Magic, and Support. Each plant has an upgrade tree in the form of 3 paths, each having 5 tiers, counting a total of 15 upgrades. But a player can only have 9 upgrades per plant, 5 tiers on one path, and 2 on the others. And only one 5 tier upgrade of a tower can be placed on the map, for example two 5 tier Peashooters can't be placed on the map, only one is allowed. On the 4th and 5th upgrade of Path 2, a special move called Activated Ability is unlocked. When the icon is clicked, the said tower executes its ability. Each ability has a cooldown, before it can be used again.

There are additional two plants which do not have upgrades and are rather cheap. And they are to be placed manually.
