Starting in January we will be releasing the Battle City Tournament Kit which is only available at  Konami Official Tournament Stores (OTS)!  These kits will support either a one-day tournament or a weekly tournament format.  Check with your local OTS to see which type they’ll be running, and from when!

They’ll be Battle City Game Mats and token cards as prizes for this new format!

Each kit contains 1 Game Mat and 3 Super Rare Token Cards (from a pool of 6) and 1 Super Rare Battle City Token Card!
