Ms. Spartan in DOA4
I hadn't heard this anywhere before, so in the off chance that you weren't aware of it . . .
Link a la 1up.com
Apparently the Halo 2 playable fighter in DOA4 is a girl Spartan. Giving DOA's usual propensity for skimpy costumes and advanced mammary physics, I was pleasantly surprised to see her fully armored, without armor boob-slots and still helmeted. According to the article, Spartan-458 isn't a throw-away character. 55 unique moves of her own, taller than most the other characters and speedy to boot, she should be some good fun for you dual-wielding DOA/Halo fans.
