If Dishonored managed to pass you by last year and you've got a half-decent PC, you'd be mad to miss this insanely cheap offer. Gamefly's £2.99 deal price is already a fantastic saving, but plugging in the UKMAY20OFF voucher code brings it down even further. A brilliant game for a quarter of the price of a cinema ticket.
You'll get a Steam code. Many thanks to Gemsa @ HUKD!
