The Shanghai is a primary weapon for the Stealth class in Blitz Brigade. It is a crossbow / slingshot that can easily take out enemies with its high poison damage. This weapon is considered by many as their favorite weapon alongside the Heisenberg 9 and the Winslow SMG because of its cheapness, high critical chance, and overall damage. The rate of fire is decent for a Stealth's primary weapon but ammo capacity is somewhat below average. However, it rapidly surpasses the other slingshot-like weapon, the Loxley.
NOTE: This weapon can be fired more rapidly by tapping the trigger quickly while sprinting. It's rate of fire increases to around 180 RPM. This is similar to the quality of the Zeus's Razor , Frostwork , Whirlwind , and Court Cleaner.
Suprisingly, the Shanghai ignore Invincibility Tonic's effect.
