War Cars Construction Set (1987)

War Cars Construction Set is a race game where you must race against the computer around a large maze viewed from above, collecting flags. Your vehicle also carries two rocks which only one can be deployed at a time. This will block your opponent for a short time. Each car has five lives and if you crash into the other car then you lose one of five lives. The game keeps going, letting you build up a score and it only ends when all lives are lost.
