The Special Snowflake is primary weapon for all classes in Blitz Brigade. It was revealed in the Christmas 2015 Blitz Brigade update, and released for sale starting on December 23. The weapon costed ~1000 diamonds and is already premium when purchased. But it's never for sure how much it will cost because it keeps dissapearing from the Shop every year.
Special Snowflake launches impact explosives in a linear trajectory, similar to the Demolisher's primary weapons. The damage and rate of fire mimics that of Q27 Predator. However, the Special Snowflake has two considerable differences, it does approximately 100 more damage, and it can slow down opponents if you have the cards to fuse it which is considerably strong being a splash damage weapon with a large splash radius. Once you're caught by one of its explosions, it is very difficult to retaliate or escape.
