Mega Man X2 is the 2nd game in the Mega Man X series for the Super Nintendo. It makes a particularly interesting run as there are many weapons that can be used to increase mobility. These include a grappling hook, a fast mid-air dash, and a weapon that can transform enemies into platforms.
McBobX takes a different approach and chooses not to collect any upgrades and only uses the X-Buster weapon to complete the game.
We also have an "X-Buster only" run for the first Mega Man X game which you can watch here.
