Mega Man ZX Advent/Train

The first level where you control a Biometal, namely Model A. Buckfire is waiting for you at the end!

After being ambushed by Promretheus and Pandora, you'll fuse with Model A to form Mega Man A, who is reminiscent of the X Series' Axl.

Main Area
When you start, move to the right, and take out the 4 gun mechanaloids, 3 shots each.

Jump onto the platform to take out the rocket mechanaloid, also 3 shots. when you reach the bottom, there is a mech that shoots rockets, but differently from the previous one, this one a bit harder, taking 8 shots to destroy.

Jump on the next carriage to take a rocket mechanaloid, and below it is a rocket mech to take out.

The next carriage has 3 mechs dropping grenades. use your homing attack here, which will deal with it in one shot.

Shoot down one more rocket mechanaloid to advance to the boss room.

Boss: Buckfire
