When performing Omega Shot, Omega loads his right forearm and opens up for the artillery in it, revealing several gun barrels. He then fires a yellow spray of pellets powerful enough to blow away anything in close range ahead of him while reeling back from the shot.
When performing Omega Shot in gameplay, the player can attack close-up enemies, but it cannot hit enemies over long distances, unlike the Lock-On Shot. To use Omega Shot in gameplay, the player has to quickly press /.
- In Sonic the Hedgehog: Official Game Guide, an error says that the Omega Shot uses homing lasers to attack foes instead of pellets. The attack it is referring to is the Lock-On Shot.
- Strangely, when Omega attacks Mephiles the Dark in a cutscene with what appears to be the Omega Shot weapon, he seems to fire singular rounds instead of a spray. Given that each shot seemed to come from a different barrel each time, this could mean each barrel has one pellet stored in it, firing eight total pellets at once. This could also mean the Omega Shot works similarly to a shotgun, which can fire pellets or "shot" stored in a shell for a wide spread or use a slug for a single more precise shot. The latter theory is more credible considering how the Omega Shot only has an effective range of about 4 feet in-game and pellets fired from a weapon with such a short barrel would have a similar range.
