Perfect World's monster-hunting MMO, RaiderZ, is currently in closed beta. You can get in right now by claiming one of 15,000 beta codes that we're giving away courtesy of Perfect World Entertainment. We'll be playing the game for the first time along with you, so in lieu of any descriptive text based on our own experiences, here's something from the fact sheet:

"Experience the heart-pounding thrill of the hunt where the line between hunter and hunted quickly blurs. Track colossal-sized monsters online in an open world that is as beautiful as it is deadly. Will you discover the origins of the monsters' invasion and where their taste for human flesh comes from? In an exotic land overrun by hideous creatures, the country of Rendel has put out a call to all able-bodied adventurers. Know your enemies and choose wisely your allies. Many have perished before you. Now, hunt together. Or die alone!"

After claiming a key, head on over to playRaiderZ.com to redeem it. You'll receive a confirmation email and instructions on how to download the client as soon as it becomes available. The closed beta is expected to run for between four and six weeks. In addition to beta access, signing up via this giveaway will net you exclusive in-game items that include soup feasts (there's an "Epic Dinner Time" feature apparently), experience buffs, and a guitar that serves as both a social item and a weapon.

NO PURCHASE NECESSARY. Offer open to registered GameSpot members. This offer may be modified or terminated at any time without notice. Offer expires when beta keys supplies end.
