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.
