User blog comment:GSFB/Orcs vs Zombies/@comment-5063947-20130108001219

I say the Zombies win this one for a few good reasons. Even though Orcs are more smart, they must likely won't know they must destroy the brains. Plus the zombies are best working with groups if their are 3000 of them, then you are most likely screwed. Plus the moan can summon more zombies incase it  needs backup which can make the Orcs panic.
