The Firestorm is a primary weapon for all classes in Blitz Brigade. It is a weapon that was at first obtainable through a tournament (receiving the non-premium version), although later it can now be bought with coins while still having to upgrade it separately. It does very good damage with a higher fire rate than any of the already premium weapons in the shop, and shoots incendiaries rather than bullets or something sci-fi related. Don't be fooled by its great stats, because there are a few letdowns. The range relatively short, and the critical chance is only at 0%. It isn't based off of anything.
- This weapon suffers from the 1 Damage Crit Bug when equipped on the Soldier or Sniper.
- The premium upgrade price has been reduced from 1200 to 1000 diamonds. Either way, this make the Firestorm currently the highest costing gun to be upgraded to premium probably due to the fact the Firestorm is for all classes.
- It is somewhat in resemblance of a Browning Automatic Rifle due to it's magazine size and rate of fire.
