You have the newer achievements, you need 900 from the old achievements then it will never glitch up, same with katana and security helm.
There is no glitch.
yes
No such thing they patched in since halo 2
No, there is not.
Yes, there is a Security armor in Halo 3, Only the head and shoulders are unlockable.To get the head, you need the gamerscore in Halo 3 to be 1000g/1000g. And for the shoulders, the gamerscore is variable from 700-800 for some reason. (Note: If you get the shoulders, there is a glitch that makes you lose them when you earn them, but don't worry, they return back.)I hope this is useful!

Nope. Sorry.

You can't. There is no glitch for unlimited life.

You can not glitch to rank 50. You have to play ranked match's until you reach that rank.
You have to get 1,000 gamer score on Halo 3.
