The Shock Cannon is the fully upgraded version of the Shock Blaster. In addition to more power, the Shock Cannon also changes the charge-up ability the Shock Blaster gained at V2. Inst ead of firing a more powerful, blue blast (which it now does all the time), releasing the fire button after charging will fire a spectacular Beam of Death. This beam covers a long range, and will destroy, or at the very least significantly damage, all enemies it hits in the early levels.
- The Shock Cannon is the weapon featured on the cover of the Japanese version of Up Your Arsenal. In fact it is also used as the example showing that weapons can now upgrade to V5 on the back of the box.
