stealth bastard dlx is a great game.. you are a clone like 47, behave like sam fisher and the levels are test chambers like portal, full of deadly traps.. level editor, global rankings and tons of chambers are included.. for 1 metal piece is a must have, no doubts.. anyway as far as i know kinguin is a site that collects users all around the world that want to sell their virgin keys maybe taken with coupons, bundles etc you have to signup, add to cart and pay choosing metods offered.. as you can see there is a feedback system like ebay.. game key will be delivered in a couple of minutes in your mail box, copy paste and play actually thief4 costs 16,77 euros, no jokes..
