Well, this is a very tempting offer. By using the voucher code above, the deal from SimplyCDKeys is made even better, allowing you to save around £10 over the next cheapest offer. Do bare in mind though that the PC version is delayed, and will not launch alongside the console version in March (despite what the listing says.)
From what I've played of it so far (which you can watch by hitting the Playthrough link above) it's certainly the Dark Souls experience but a little more refined in terms of its controls. The sense of dread is still there, the foes just as relentless, and the Red Phantoms will definitely ensure you die repeatedly. In short, this is a great price as long as you're okay to wait a little longer. Thanks to AndyWedge @ HUKD!
