We're giving away five million Steam keys in five weeks, with Bundle Stars

Later today a million visitors to PCGamer.com with an eligible Steam account can get a free Steam key. We're giving away five games in the next five weeks, each available for seven days before being replaced, with a million Steam keys up for grabs every time.

The redemption method involves giving a single Facebook like/follow to the presented Facebook/Twitter account. Once that's done you can pluck your Steam key from the page and redeem it right away.

We're running the giveaway in association with Bundle Stars , who sell games individually, but specialise in bundling them together to sell them with greater discounts. Over the coming weeks you'll be able to build a free Steam bundle from our super-secret lineup. After SpaceChem, there are four games to go. Come back each week to find out what they are, and be sure to pop by later today to get SpaceChem, which is a very neat game that looks like this:
