Do you like Tankbattles in the summerrain? Then Battle City perfectly fits for you.
A funny little shoot the enemy tanks and protect your base game that is just great.
Otherwise I wouldn't have made the maps you see here anyways.
So if you need help with Battle City you will find all maps here and you can always come back and check what you missed.
Battle City was released in Japan only but there is a version with english text out there.
