Extremely good ending

Taxonomy upgrade extras: 


umm i guess u didnt beat the game or something he said "wake me, when u need me" that means if something happens cortana will wake him up for master chief to fix wat need to be fixed. and u probally didnt beat it on legendary cuz theyy head to a planet thing where to fight the covenant, just read the is there going to be a halo 4 article and it will tell u all about it.

I took that to mean that Cortana can wake him up if she gets too lonely, but, eh, still applies.
