You guys are very wrong about BP. They do make a difference, and they are not just there to annoy you at the end of every map. Take a look at some of the premade tanks, or some of the tanks in BT1 or BT2. The tanks are rather appealing to the eye, no? Now I know a lot of us are gamers and have very little interest in making our tanks looks bigger or better. A lot of us think strategy, stay small and fast, in fact that is exactly what I did, but the fact of the matter is, is that the BP add a great way to make some pretty freaking cool looking tanks.
A bit short, also the game had a relatively hard start, but the difficulty faded as I was able to get laser towers. Good concept, but more levels, creeps, and weapons should be added. Also perhaps adding a mode where you can upgrade your character's gun would be appreciated too.
