The cortana figure is my personal favourite out of the series 1 figures. She is looks just like in the halo games, complete with transparent blue plastic, with all the writing and coding.

The best part is the light-up base which contains 3 bright LEDs that illuminate cortana brilliantly. Try this in the dark and you will be astonished how realistic this cortana figure looks. The only two bad points are that you need 2 AAA batteries that aren't supplied, and the fact that cortana has no articulation whatsoever. However, the current pose is great, and cortana's face looks very realistic.

You should buy a cortana figure ASAP! You won't be disappointed, I still hope mcfarlane creates a green and red corrupted cortana figure, only time will tell!

Looks good on a shelf full of memorabilia,the light up base is an especially good touch. Needs 2xAAA that doesnt come with it. Looks best with the lights off,lol.
