"Team Deathmatch" with teams of three players competing using adhoc mode, each round lasting five minutes each.

Qualifying rounds will take place this month on February 17th and 18th in five main cities - Fukuoka, Osaka, Tokyo, Sapporo and Nagoya. Nominated teams will then move onto the finals in Tokyo on the 25th where the champion team will be presented with a shield trophy, crest and other prizes.

All participants also receive a "Special Keycard" containing a password to unlock upgraded soldier units (something that is also included with the Japanese OST and guide book).
