Mega Man X Collection Tips

Megaman X3 ( Beam Saber )
First you need to defeat Vile MKII in stage 8 ( that's first half of the game) using either the spinning blade or the Ray Splasher. Then use Zero to defeat the MID-BOSS MOSQUITOES. After you defeat him this will trigger a cutscene. This is what will happen Zero gets caught in the blast and they hit each other at the same time. Then Zero gives his beam saber to X.

Note: That if get Beam Saber you will lose zero all the way to the end of the game, and a different ending will appear.
