Great mod, even when I was being pounded nonstop by all the tanks, it still made me go back; knowing I could actually kill the tank that was shooting me makes it worth respawning.
That being said, wow there is alot of armor! And it respawns so quickly. After playing maps like Guardian, Highway to Hell, and other tank/plane maps, it makes infantry feel somewhat insignificant. I found myself having to choose the AT class 4/5 times that I spawned.
The level designs are awesome though. I like all the grass and shrubbery, it makes having to cross an open field that much easier.
I only ran into two problems entire time were significant. The first one I found was that you won't hit crap if you don't have a decent connection (<120 ping). This is not the developers problem, but merely a warning to anyone with slow connections; expect to die alot as the enemies run circles around you and you fire wildly behind them. It can get annoying, but its still good fun
The other problem is one that I thought could easily be fixed in the next patch version. This is the vehicle entrence "bug". I found myself having to run in cirlces around the car/tank trying to get in. It appears that you can only enter a vehicle from the side or top, and at a specific angle. Getting in from the back or directly in front will not work. This is a minor issue and really doesn't effect the gameplay aside form the waiting period.
These guys made a great mod, and some aspects are even better than BF2 I think. Most of the weapons are powerful and accurate and you get a sense that you can survive on the battlefield, even if your outmatched.
