Mega Man X3 is the third game in the Mega Man X series, and the last one to be released on the SNES.
This is the second "100%" run of this game. agwawaf
speeds through the game very rapidly, collecting all heart tanks, subtanks, Ride Armor modules, upgrades and finally the Golden Armor. However, Zero is kept alive and his Z-Saber is not obtained, so the author could get the best ending.
The page Mega Man X Tricks
