"You are attacking a castle using a path...
You are likely to have a fireball spat at you by a GRUE."
this is nice, good color and lighting, and the 3 basic towers of any game.
Cannon: Air/Ground: heavy hiter, this tower is used for doing maximum damage to single targets.
Machinegun: Air/Ground: rapid fire, this tower is used for killing swarms of weaker enemies or taking out weakened ones
Anti-Air: Air ONLY!: air killer, this tower is designed to engage air, keeping your other towers able to focus on ground targets.
