Particle Tower

The particle tower is available after the laser tower is researched. It is one of the more expensive towers to research, build and upgrade. It does not target air but it's intense rapid-fire punch can make quick work of ground targets. Beside cost and targeting deficiences, the only downfall is that it overheats quickly, so theoretically it is better against enemies it can kill within a burst so that it can flick to another target and fire at them.
