Mega Man X2 makes a particularly interesting run as there are many weapons that can be used to increase mobility. However, many of these weapon abilities require the use of the X-Buster upgrade, which is skipped in this movie. In fact, in this movie, FractalFusion does not collect any of X's upgrades! However, he does rescue Zero by fighting three optional X-Hunter battles. This is arguably the hardest set of goals to accomplish in a run of Mega Man X2.
This route was designed to have the exact opposite goals of this run, which collects all upgrades but skips saving Zero. With this run, however, the bosses near the end are no longer defeated in a single hit, showing off more of their AI. Also, due to the items collected, there is an easter egg in the ending credits.
