MAPM9, Diamond Blizzard Zone, is the tenth Match level in Sonic Robo Blast 2v2.1. It is a very large, multi-leveled stage that takes place in a snow-themed palace and its surrounding outdoor areas. It debuted in the May/June 2010 OLDC, where it won the Match division with a score of 7.88. The name is a reference to Cirno's spell card "Diamond Blizzard" from Touhou Koumakyou ~ the Embodiment of Scarlet Devil.
