I give this a 5/5!!! I think i beat the bosses and got to the fifth upgrade. I prefer the balanced tanks with a little more power. I played the first game and it was good, but i liked how in this one you can have options on upgrading, you can change the controls during the game, you can view a map, how you have a secandary weapon (etc.) I just love this game!!! :)
i give it a 4/5. i would give it a 5/5 but it is too easy. the second one is harder and has a few things fixed that i thought needed a little tuning up, but all in all it is a good game.
