More of the same, less of the good stuff...
Graphics - Well, pretty much the same, which can be expected from a expansion type addition to the genre. Explosions were nice, but other than that it really just felt like I was playing the same game over again.
Gameplay - A couple of new additions, the ability to take control of a tank was nice, but short lived. AI was decent, but clumbsy and got a bit annoying at times.
Overall - I would have expected some nominal improvements to the game, but what I got was more of the same with the fun of the original gone.
Unless you are a die hard for the first series in this game (and I thought I was) I woud stay clear of this one.
