From Sonic Retro
|Game: Sonic Unleashed
|Affiliation: Eggman Empire
This robot is similar in design to other Egg Fighters, but is a different color - slate-grey rather than purple-blue. The Egg Shooter attacks by shooting bullets akin to a Gatling Gun style for a few seconds, as its sole method of attack. During daytime stages, the player can easily move around them to avoid their fire, while in nighttime stages the player can easily guard against their shots without losing too much of their shield.
These robots usually appear in larger groups with other types of enemies, but there is rarely more than one of them in each location. In rare instances, there can be a pair or group of them found in Rooftop Run and Eggmanland.
|Custom cannons mounted on these Egg Fighters' arms snipe at Sonic as he races past.
A special upgrade allows them to keep on fighting, even after their body is destroyed.
