Welcome to Gaia! ::

You go to the event forum and post in the battlegrounds.
You can attack Vampires or ask to get bitten by them.
You have a set number of hit points that decrease with every three attacks on your post. If you dont go back to your base before they're empty, then you become a Vampire(Vise versa with vamps)
The more of the opposing side you attack, the more points you get. The more points means the more rage abilities you can use and the higher your Rank, to say nothing of rewards.
Rage allows you a better chance of hitting an enemy. Each ability costs X number of rage points.

They got prizes.
I just recieved a black widow spider tattoo, though I havent been hunting long.

The Bee Movie is crap.
The Bee Movie Gun is comically oversized, mishapen, and awesomely effective.

The Marketplace
Like hell if I know where or how to aquire it but it only cost me a couple hundred bucks.

And it looks amusingly lethal. Seven barrels of insectoid developed death.

I'm working my way to getting a chainsaw.
Mwahahahah....

Yes.
Get enough Hunter points and you get a Chainsaw.

I'll try hunting again in a bit.

I'm waiting for Gaia to stop being stupid.

I just a moment of pure f-ing genius.

How about if they did NOT force you to change sides by being ganked in the battle.

That way, we wouldn't have a 100-1 Human to Vampire ratio because they wouldn't be getting wiped out.

Just have it done like the water balloon fight.
