So my sources tell me...

L4D2

Witch doesn't sit there sobbing like an emo kid anymore;
that's right she roams now!

Zombies auto-aggro and run right for you instead of
letting you stand a few feet back and admiring their

and yes, I know it's the exam period,
and yes, I am a colossal dickweed for sharing this info with you all now.

Thank you.
