The tank models look cool, and I couldn't help but move my head along to the soundtrack you used. Voice acting was also a nice addition. However, I felt there was a lack of animations on the tank, additional sounds like explosions when missiles hit, or the heavy sound of the tank engine as you move through the level. Camera was a bit weird to use to me as it had a pivot behind the tank model instead of it orbiting the tank like in other third person vehicle combat games I perhaps am more used to. Additionally, the exploding tanks were cool but there were a few times when I did get stuck on the remains of my enemies.
Nevertheless, good job on your submission :)
