I'm looking for this game, hopefully someone made it for mac, but if not, the pc version is fine too. I used to play it every day at recess, probably 7 or 8 years ago. This is what I remember about it, you picked your tank, and then went to this 2d battlefield. You picked a spot on the field, bought the different types of ammunition and bombs that you wanted, and then entered values for arc and speed and stuff. basically you had to compensate for where you were on the map, and wind speed and stuff, and try to blow up the other player. If anyone could lead me to this game, I would appreciate it SO much!
