I got a beta invite today, only played one map so far, but it's pretty cool. Asymetrical balance in a strictly-PvP game is a fun idea. It's similar to CS, except there really was no difference between T and CT in CS, while vampires and humans are completely different.
Definitely going to give this game more time. It needs more marketing, too, when I asked about it on another forum, the common reply was "Nos-what"?
