The Gun Tower is the very first tower that a player starts off with. It's capable of dealing low to moderate rapid damage to a single alien at a time, provided the alien is in line-of-sight of the tower. It is also the cheapest tower to produce and upgrade, resulting in being a very common tower to be used both offensively and defensively. The Gun Tower is also the primary choice for shaping paths on more open levels.
