Cortannnnna.
MMMMmmmm... Cortannnnna
I actually thought she was more attractive in Halo with the short hair than Halo 2...maybe because I got used to my glowing purple Cortana dol...err...action figure [and what a figure ;-)]...men buy action figures darnit ;-) LOL
But long hair or short any superintelligent shining sleek gal who can virtually read ones mind [and hey if shes purple and named for a sword all the better] has to be quite MMMMmmmm indeed.
