Siege Cannon

The Siege Cannon is the 24th weapon available and was added during the Elysium update. It has 90 bullets and boasts extremely high damage, high range, and moderate accuracy and agility. It is unlocked at level 36 costs 500 gold.

Strategy
Apart from being the only heavy weapon in the game to have an agility of 2, its accuracy seems to improve drastically when standing still, having a very high rate of fire making this weapon a tactical heavy weapon, able to take out a lot of people in short time. But the reloading speed is that of the Heavy Machine Gun. You are still prone to counter attack, but you are at least able to move faster. Also, stand still when firing as accuracy will drop drastically when moving. Standing still will help you hit targets farther away since the weapon has long range.

Overall a good weapon to have as well as the fastest-firing heavy weapon in the game, but the price tag makes this weapon not worth the price.

Blizzard
Blizzard carries this mighty weapon around, eliminating all that he sees (although he barely stands still to get accurate shots).
