The Spear Gun is a primary weapon for the stealth class in Blitz Brigade. It is a gun that shoots deadly spears, which can kill any class with 1 or 2 headshots from this weapon. It has a decent rate of fire, quicker than the Heisenberg 9 but slower than the Quiet Knight. The range is average, but the critical chance is higher than Heisenberg or Quiet Knight. However, like the other two, the ammo capacity is quite poor. It is the third most devastating primary weapon for the Stealth, behind the Winslow SMG and Vampire's Bite.
