Atari's Battlezone

Battlezone is a vector-style game.  You are piloting a tank around the battle ground trying to avoid and hit enemy tanks and space ships.  There is simple terrain and obstacles to hide behind.  It is very green and seems like a game we would make in to a free app for phones today.

It is clear to see how this game quickly progresses.  As an arcade game is could eat all of a child's lunch money in an afternoon.  There have been many versions of this game made today.  Tanks is a good example of a game based off this game.  I did not realize until it was pointed out to me that you could shoot at the spaceships and get more points.  Its a good classic war game.
