Valve have decided to let gamers get Portal(one its most popular titles) for free. I should warn you, that this offer is only valid until 20th September, so I suggest you jump on this one right now. It’s available through steam on PCs and Macs, as well as on Xbox360 and PlayStation 3.
To get your hands on this freebie, you have to have a Steam Account. If you don’t have a Steam account, then you can create your Steam account by clicking here . By the way, I should mention that it is completely free to create a Steam account. There are no monthly subscription fees, no signup fees or any other fees. In addition to that, you can also use PayPal as your method of payment.
Once you have created your free account, click here to get steam for free.
