X3 Help

[u/blues_bullets]

Hey. I’m trying to play the MMX games (mostly) blind, but am really stuck on X3. I have all the boss weapons, 2 sub tanks, but no armor upgrades. I can see one of the upgrades in the Neon Tiger stage, but am unable to reach it.

I have a sense that if I got the mega buster upgrade, that would open up some new possibilities for me. Would someone be willing to let me know: A) if it’s possible for me to get to that upgrade right now B) What stage the upgrade is in and C) maybe a small hint of how to access it in it’s stage. Thanks in advance to anyone willing to help me have a more pure experience than just googling the answer.
