In Mega Man X3, you will find yourself finally
using Zero's coveted sword. The author speeds
through the game very rapidly, and uses the sword
to beat the 8 bosses very quickly the second time around.
This run is a whopping 3:45 faster than the last version,
both by using some new tricks and playing with a lot more precision.
The airdash was judged unneccesary and skipped.
The page "Mega Man X Tricks" explains some of the tricks
that are and/or can be used in the X series games.
