: Hey guys we’re back with a new tutorial on how to get to Cortana on
: Floodgate! This is a pretty interesting trick, it wasn’t until recently we
: found out that Cortana’s biped is actually loaded during certain parts of
: missions. Normally you never see Cortana in game other than cutscenes. But
: during those annoying Cortana moments, which happen throughout Halo 3
: campaign, a Cortana model needs to be present on the map. In most cases a
: black box appears with the Cortana model inside of it, she only appears
: during those special in game moments. On Floodgate we managed to figure
: out her coordinates and came up with a plan to get to her as she appears.
: We’re currently working on plans to reach her on other missions as well
: but for now we hope you enjoy this one!

Huh. I never really think about the stuff that has to get loaded into the maps (like the bridge for the cutscene) so it's fun to see tricksters thinking a level above and figuring this stuff out. Fun video!
