I made it to Chicago so far! It's what I expected from you: A nearly perfect Flash game. The graphics, voices and sounds, the whole design, has that spot on arcade vibe written all over it. I haven't seen the whole game yet, but so far it's just awesome! The only thing I was a bit sad about is that I couldn't use my laser to shoot the enemy cars on the battle field. (Or could I?) But that would brake the gameplay perhaps. HOWEVER, you did a fantastic job in making a game that looks, feels and plays like a flash game in its best days!!
Edit: Now I got it. I should be more concentrated when reading textes.. It clearly says that the ground units can't be hit by the lazer.
