The Shock Cannon is a Fallen weapon that is wielded by certain Splicer Captains and can also be picked up and used by Guardians. It is dropped from Shock Captains during certain missions. It fires arc energy projectiles with each pull of the trigger, and is strong enough to smash a Sparrow with a single shot. Each cannon holds 10 shots.
Damage from the explosion does not affect the Guardian using the weapon.
The Shock Cannon behaves almost identically to the Scorch and Null Cannons, but its projectile can only charge up for two stages of power before detonating. The Shock Cannon also has slightly different sound effects than the Scorch and Null Cannons.
