What would a Tower Defense game be without some proper tower. The following towers can be build with gold. All towers are upgradeable from Level 1 up till level 3. As towers upgrade they will do more damage at a lower cost level as compared when building a new tower.
Building new towers VS upgrading existing ones in a trade of by spending more money on extending the maze or having a smaller maze path while doing more damage. It will all depend on the wave of incoming enemies of what works best.
The Gun Tower
The Gun tower is a basic 3 barreled gun tower. It offers low damage at low cost. It can be used to block enemy path and create a maze of towers without cutting deep in your gold supply. The turret targets the first unit in its range and will lock on that unit. While locked the does only damage the first unit that will be hit by its bullets.
When upgraded each level adds 1 more triple barreled gun to the tower. When fully upgraded to will pack medium damage.
The Tesla Turret
The tesla turret is your backbone of the maze. It will offer medium damage at medium cost. this turret will zap enemy units pretty fast specially when they are in groups.
When upgraded the damage output of the turret will increase as the Tesla will be powered by extra coils. Every upgrade makes the arc hit one additional target causing 3 targets to hit with full damage at lvl 3 upgrade.
The Path Block
The Path blocker is a simple wooden frame that will block the enemies path forcing them to find a way around it. This blocker is very cheap and can be used to extend the maze of turrets at very low cost. It is effective at controlling the path the enemies take and at the same time it will provide you with a platform to gain elevation and get a better overview of the battlefield.
When upgrading the Path blocker it will gain strength by adding Rocks or upgrading to metal. Each upgrade offers more resistance to enemies that will attack turrets.
