Python

Python is the 6th prestige weapon unlocked in the game, and easily the most bizzare of the prestige arsenal. When activated it shoots out a snake that flies through the air and begins exploding repeatedly when it lands, the direction it goes in is completely random, this can hinder your shot due to the fact that even if you get a direct hit sometimes the python only gets a few shots off and then leaves in some other direction, ignoring the tank completely, its targeting system is a bit of a mystery and it is unknown whether or not the weapon even sees the tank. It can move anywhere on the map, even through air, and does not care about what shape the terrain has. 
Pros:
If you're lucky the python will burrow into the ground and take the enemy with it dealing massive amounts of damage.
Ignores terrain and doesnt bounce around.
Cons:
Could easily avoid the enemy tank and move in some other direction.
