Complex Number

The Complex Number is tier 5 tank that upgrades from Fractionalizer.

Design
The Complex Number has a design very similar to the Fractionalizer, with the exception of the color of the barrels, which are green and purple rather than black and white, respectively.

Technical
The Green drones (fired from the green barrel) on shift or right click (aka alt-fire) act similar to the L-Sys' golden traps. i.e. they explode into small bullets. The purple drones function as normal drones.

Upgrades
The Complex Number upgrades from the Fractionalizer at level 60 and doesn't upgrade further.

Trivia

 * In mathematics, a complex number is the sum of a real number and an imaginary number or something, or just an imaginary number, I don't know, I still don't understand imaginary numbers.
 * I think an example would be the square root of -1, but I still have no idea what an imaginary number is.
