Games appearances

Sonic Adventure 2

In Sonic Adventure 2 and Sonic Adventure 2: Battle, it appeared as a boss after completing the City Escape stage.

Shadow the Hedgehog

Big Foot also appeared in Shadow the Hedgehog,[2] where it is slightly darker in coloration with some silver outfit, and has very solid armor that is more powerful than R7's. In gameplay, they are separated into two variants:

Big Foot Type A


The Big Foot Type A in Shadow the Hedgehog.

This variant is the most basic and common type in the F6t Big Foots series. Like all other enemies in the game, the Big Foot Type A automatically walks and attacks without spotting a target. Also, its walking programming is limited and it can only walk a short distance. It is equipped with the Gatling Gun to shoots bullets that are very fast and cover a great distance. In gameplay, this type can be easily ignored since the player must be in a close range to it to make him attack, but not always. It can also fly, but very slowly. It takes nine hits with the Homing Attack destroy it. Once destroyed, it awards the player 500 points, and its gun can be picked up by the player.

Big Foot Type B

The Big Foot Type B in Shadow the Hedgehog.

The "Big Foot Type B" or "F-6" is a more powerful variant than the A type. Aside from its color scheme, the Type B looks like the Big Foot in Sonic Adventure 2. It is equipped with 8-Shot RPG that lets it lock onto the target and launch quick bullets at the player. In gameplay, It is usually in "stand by" mode until the target is in range (if it is not airborne). Unlike the Type A, its programming lets it pursuit its target and it can even destroying objects the player hides behind. Its armor is also tougher as it takes fifteen regular hits to destroy it. Much like the Type A, it can fly. It awards 1000 points when destroyed. It appears in The ARK, GUN Fortress and Black Comet.


Hot Shot

The Hot Shot is exactly the same as Big Foot, with the same weapons and capabilities. However, it also has an added lock-on laser its front. Hot Shot is deployed to fight Shadow when he was set free from stasis by Dr. Eggman.

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 has been dealt, the Flying Dog simply stops using missiles and machine guns, and instead just launches the plasma cannon repeatedly. It was deployed on security hall against Rouge the Bat, who was stealing three Chaos Emeralds from the vault.


Boss guide

Big Foot begins by flying up and strafing the ground with machine- gun fire. It’s easily seen and he’s not moving very fast. 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 you. Again, run around the edge of the circle until the barrage stops. Try to time it so that you’re close to Big Foot when the bay doors close. As soon as they do, leap high in the air and Homing Attack on Big Foot’s cockpit. After the fourth hit, Big Foot collapses.

As an easier way to defeat the Big Foot in less than a minute, the player can jump on top of containers before it destroys them, and launch a Homing Attack into it.
