ONLY RULE: Have the courtesy to say when you've taken the keys.

£20 worth of Runes of Magic items (does not work in Australia or US. Possibly UK only or expired?)

Items include: A golden ostrich egg that grows into a mount, a luxurious two-storey wooden house with basement, potions of experience and skill that last a day, a "nice surprise orb" that yields a random item, a basic weapon driller that lets you slot runes into your gear, a transport rune, a basic experience charm, an advanced moon jewel for buffing your armour power and a scroll to transport you home. Worth 579 diamonds in-game.

Log in on the website and go to the redeem code section on the site. You'll be given a shorter key to use in the in-game store.

This one likely doesn't work any more, but it's worth a shot. (Confirmed to still work)

Six free games on GOG.com (usable by everyone)

This only works on new accounts, so you'll need an alt if you already have one. Games are Ultima IV, Beneath a Steel Sky, Tyrian 2000, Lure of the Temptress, Teenagent and Dragonsphere.

Go here and sign up. Games will be added immediately.

Spoken to Cult about this link. While it could be construed as a referral link, it's been allowed on this occasion as it's necessary for the games.

Update: Seems to have been a timed exclusive that's now available for everyone. If you already have an account, going here will be simpler for you.

£5 of in-game money, a stats boost and a flag for 8Realms (UK only?)

Taken keys

Just here for prosperity. Some of these may be repeatable, but that would be your job to test them. If you find they are, tell me and I'll put them back up above.

Edit: This was a Tribes: Ascend beta key, but I was apparently last to the party and it's now in open beta.

Discovered this key hanging around in a PC Gamer mag. Only just thought about throwing it up here.

Well, fuck, my Settlers Online key is also useless. As is my Victory racing key... Goddamn it, developers, stop being competent.

Have more things incoming and I think I'm out of closed beta keys, so let's have more luck now, shall we?

Once the game has started, press Escape and go to the Arms Marketplace. Click Redeem Code and redeem it. Your car will be mailed to you (as a non-player, this sounds totally ridiculous).

How do I redeem my code?

Your first step is to visit the redemption site. You'll then be taken to the World of Tanks homepage. Once you're on the WoT's site, log in . Click Get Gold and select the £5.95 option. A new pop-up will appear with payment methods. Click "15 more choices" and then "Ultimate Game Card". Enter the pin.

If you're a regular player, you can also use the card as a discount to a larger purchase of gold: just select the amount you wish to buy.
