Helpful glitches

[rabidmidget]

I know there has been many glitch threads but none that i know of about helpful glitches. When i say helpful glitches I mean ones which you accidently found and helped you somehow in the game.

The most recent one which has happened to me was that after completing the last level on halo 3 on legendary for the first time, i simultaneously unlocked 4 achievements and then i somehow unlocked katana and security armour which usually require 49 unlocked achievements but i only have 33. This is the only one i can think of at the moment.

Well, when you beat it on legendary, it counts it as beating it on easy, normal, and Heroic, too. And it's 49 achievements OR 1000 Gs for the katana if I remember correctly.

I already knew how i got the 4 achievements, but i only have 935 gamerscore in halo 3 and 33 achievements thats the part which makes me think it's a glitch

Sequence breaking on Metroid Prime. I had the space jump boots, 10 missile capacity, and two extra energy tanks before the morph ball boss. With the space jump boots already in my possession, I grabbed the morph ball upgrade and jumped over the fence.
Later, I fought Thardus with the plasma beam.

That cinnabar glitch in Pokemon Red/Blue was pretty nice. Infinite rare candies and master balls? Heck yes.
