Yo just thought I'd share this find with you, was going about my day and a friend linked me to G2A, it sells discount games so you can get really cheap steam keys for games! My mate wanted me to get dead rising 3 (Not played it unsure if I should buy it or not if you've played it let me know if it's anygood, it's like 15 pound on that site atm) but wasn't interested, just before I clicked off the site I saw titan fall for 12pound! Made me so happy been after this game fooor ages! but it's normally like 25-30 pounds.
The site is amazing and I really encourage you to check it out if you like gaming, some of the awesome discounts on there I was at first worried if the site was legit, but payment is all done through paypal which is very safe and it worked out very well for me, I'm very glad I gave it a try.
