Snag a Mu Online, Flyff, C9, or Rappelz key in honor of Webzen’s 8th anniversary


Webzen is celebrating 8 years of MMOs today, kicking off multiple events and patches across its games: MU Origin has posted its 1.7 update with multi-server “Battle Core” events and two new dungeons, while MU itself has opened up part one of its 12th season of play, which features the Nixies Lake map, new gear, and the Vanaheim server.

In honor of the anniversary, the studio has granted Massively OP 1000 keys that can be applied to one of four of their games (Mu Online, Flyff, C9, or Rappelz) so you get to pick what you’re getting!

Click the Mo button below (and prove you’re not a robot) to grab one of these keys!

No keys left! Sorry.

Here’s the deal with these codes: You can use our key only once, on one account, and you have to pick which Webzen game you want it to apply to. Choose wisely because each game offers a different set of rewards!

To redeem your code,

1. Go to
2. Log in with your account
3. Select the game, country, server, and character you want to receive the item(s) on. The options in each category will vary for each game.
4. Enter the code (without hyphens)
5. Click “Redeem Code”
6. The item(s) will be delivered to the account or character that you have selected.

If you are new to WEBZEN, you’ll need to create a account, go to to download your game client and install it, then choose your server and create a new character. All codes expire on July 30th, 2017.

Standard giveaway notes: If there’s no captcha or Mo button and all it says is “No keys left! Sorry” in big letters, then we’re out of keys. If we get another batch from the studio, we’ll send out a note on social media. Having problems with the captcha not working? Try an alt browser or clear your cache. And finally, hang on to your code! If you lose it after all of our keys are given out, we cannot retrieve it for you.

Good luck and have fun!

Grab a key, then watch as they shut down whatever game you loved in only a few weeks/months! Then wait patiently for another announcement that some other company is bringing back that same game! Yay!


Since I once had a gpotato account I’m not allowed to have a webzen account for some reason.
