Hello All, been playing around with the Tanks concept, and came up with this.
These are 100% place holder assets, and a pure hobby project that if it sees the light of day will be in more videos.
It is 100% session based multiplayer friendly like any good MMO system 
this is the MMO system I incorporated into my project.

If you are interested in seeing a multiplayer video let me know I will get one up and running.
