Want a free game? Of course you do! Well, you can bag a free Steam key for one of six games (see below) just by signing up to Green Man Gaming's social hub and rewards network, Playfire.
Here's what you have to do:
- Create a new Playfire account. Click here to register >>
- Go to "Settings" and link your Playfire account with your Steam account.
- A random Steam key will appear on your Playfire profile (My Rewards) or mail.
It's not just any random Steam key, though, you'll receive a key for one of the following: Sanctum, Postal + Steam Trading Cards, PixelJunk Monsters Ultimate + Steam Trading Cards, Speedball 2 + Steam Trading Cards, Gun Monkeys + Steam Trading Cards, or Canyon Capers + Steam Trading Cards.
If you're not particularly interested in Playfire, you can just take the code and run, though if you're a PC gamer it might be worth investigating a little more as Playfire also operates as a game tracking service, and has started dishing out occasional rewards for playing the games you love.
