This is a simple player carriage that allows you to fire on your opponent and
not worry if you are moving away from their fire. Once you get in it starts
up and makes a full square around the base. You are free to fire from it at
any time. The advantage is that you are a moving target and you can
concentrate on hitting instead of moving away. The second advantage is
that the carriage provides a higher point of view on those environment maps.
If a player is killed in the turret while its running it will complete a cycle
and stop. If you jump out of it, it will complete the cycle and stop. Although
I don't suggest jumping out of it since the max height it reaches is about 600
units :)
