These models are slightly darker in coloration with some silver highlights, and have very solid armor that is more powerful than R7's. Both of these enemies are classified as Big Foot models.[2]

Big Foot Type B

Main article: Big Foot Type B

The Big Foot Type B is a variant that utilizing 8-Shot RPGs to attack the player, with it's AI being far more advanced than the F-6 variant, and appears only in the later levels. Because of such, it is one of the strongest enemies in the game, being G.U.N's strongest unit. After being destroyed, it drops a lock-on missile launcher.

R-1/A Flying Dog

Main article: R-1/A Flying Dog

The Flying Dog is basically the Hot Shot without legs. Without the walkers, Flying Dog remains hovering during its operation. It also has an improved defense, as it takes five strikes to destroy. When four strikes have been dealt, the Flying Dog simply stops using missiles and machine guns, and instead launches the plasma cannon repeatedly. It was deployed in security hall against Rouge the Bat, who was stealing three Chaos Emeralds from the vault located within.


Boss guide

Big Foot begins by flying up and strafing the ground with machine gun fire. It’s easily seen and does not move very fast. The player can run in a wide circle to avoid it. After a few passes with the machine guns, Big Foot will land and the Missile bays will open. Predictably, Missiles shoot out at the player, who must once again run around the edge of the circle until the barrage stops. As soon as the missile pod's doors close, the player must leap high into the air and Homing Attack the Big Foot’s cockpit. After four hits, Big Foot will collapse.

As an easier way to defeat the Big Foot in less than a minute, the player can jump on top of Wooden Containers before it destroys them, and launch a Homing Attack at it. It is also possible to hit Big Foot's cockpit with a Bounce Attack while it is in the air.
