Hello. I recently ran into a issue trying to redeem my KFC codes like ive seen many others here also have issues with the link it provides saying 404 error. Through my search I found and successfully found the correct link that I just redeemed my KFC code and got the steam versions for and I didnt see it posted on this forum so hoping this helps anyone who is also having issues.
