This is a walkthrough for the video game Mega Man X3. This page describes how to beat the boss Gravity Beetle and his level. 

Make your way to the right and inside the building. Here you come across a series of platforms all of them containing a reploid of some kind. Climb the platforms and go to the upper left, to the left is an indent with a heart tank behind several blocks, once you defeat the robot boss of this level the blocks will disappear.

Continue to the right of these platforms and up the ladder on the far wall. Then climb out of the opening in the ceiling. Continue to make your way to the right and into another mini boss room. After the room use the ladder to climb up. Here climb the left wall and you will see an item for the frog robot armor on a platform. You will need the leg upgrade to reach it.

With the item collected make your way to the right up and over the area and to another ladder. Take the ladder down and then go to the right. Here you will find an elevator, ride it up to the top. Here enter the room to the right, climb up the left side and you will find another robot ride armor platform. Continue to the right and you come across a series of platforms that will fall out from underneath you.

Continue making your way to the right and up the next vertical area. Continue going to the right and you'll come across to blocks that you can destroy with the ride armor. Inside is the head chip power up. Now climb the walls and at the top you will find the boss of the level.

Gravity beetle will throw balls at the wall that will grow in size and bounce around the room or a while. He will also start to glow and charge along the ground. Jump over him and move away from the bouncing balls to avoid taking damage.
