Mega Man X2 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.

This TAS obsoletes the "low%, best ending" as well as the "all upgrades" runs, since it collects all the parts of both X and Zero. It became possible to separate the "full completion" branch from the "any%" one after it was found to be faster to forgo acquiring the Shoryuken in the latter.
