I would say that it's like a sheep in wolf's clothing, but I don't know that the monster itself is any more intimidating than the nun would be.
Skullgirls is finally out, having released yesterday for PlayStation Network and today on Xbox Live Arcade. The launch trailer is focused on Double, the aforementioned monster who can mimic the moves of other fighters. Shang Tsu-... Double looks pretty cool, I guess. I'm particularly amused by the Gradius reference in the trailer, at the very least.
Kidding aside, I really do think Skullgirls has a great visual style and I hope it's successful in other aspects as well. How have the first couple days of play been going for you lot?
