Initial Launch: 

A complete cluster.

Update 2.5: I have increased the mine spawns to 6.0s and have changed Player 2's primary weapon button from backslash to "L". I have also made other minor adjustments I also adjusted where both the coaxial and main gun shoot. The final thing that I added is a destruction effect to each tank.

Update 2.6: Just minor adjustments. I have made both tanks smaller so that they go through the obstacles easier, made it so that the coaxial machine gun rounds disappear after 8 seconds, and finally have made rocks destroyable.
