Omni-Cannon is a legendary sniper rifle manufactured by Hyperion that appears in the Claptastic Voyage DLC. The Omni-Cannon is obtained randomly from any suitable loot source but has an increased chance to drop from The Sponx located in The Temple of Boom.

Special Weapon Effects

State of the art. Bang bang. – Deals bonus explosive damage. Very low initial scope sway for a Hyperion rifle. Slightly increased damage.

Usage & Description

The Omni-Cannon requires some level of patience, as the weapon has a very slow fire rate. As it deals bonus explosive damage, not listed on the weapon card, Omni-Cannon is capable of doing splash damage. It can also score critical hits, meaning that it can be used as an ordinary sniper rifle, despite the explosive damage. It is particularly effective against Insecure bots due to them having helmets, that can be knocked off with a well placed headshot. The low scope sway helps the focus against stationary enemies, which can help in getting critical hits.

Athena's Fury of the Arena skill will improve the Omni-Cannon's slow fire rate, but this requires multiple enemies to be under the influence of Rend for it to work in its full potential. Storm Weaving is also another good skill to couple with the Omni-Cannon, as the weapon swapping time is quick. Also, stacking up Maelstroms will put Unrelenting into use, which in term increases weapon swapping and fire rate, although not by much. Overall the weapon is powerful, if coupled with right skills and precision.


  • Despite the fact that the Omni-Cannon deals bonus explosive damage, it is still considered to be a non-elemental weapon, allowing Nisha's Magnificent Six to include the bonus damage increase, whilst preventing any penalties when used with Aurelia's Next to Cleanliness skill.


  • The Omni-Cannon is the spiritual successor to the Cobra from Borderlands. It has the same general characteristics, as well as its own flavor text from RoboCop – in this case, Clarence Boddicker's description of the Cobra Assault Cannon from the scene in which it was introduced.
