Someone wrote to eTeknix today with information regarding a tutorial that claims to allow you to unlock every single Steam trading card for each of your games in just 2 minutes.
A guy who goes by the name of BigC90210 who belongs to ‘Northern Gamers UK’ has created a video that supposedly shows him unlocking every single trading card for all of his Steam games.
He says that by using a piece of software from GitHub called ‘idlemaster’ and by performing a few tricks, you can essentially get all your cards with no effort at all. Apparently, the program “uses a token” which connects to your account via a web browser and dupes the server into believing you’ve unlocked all of your cards.
A number of commenters beneath his video claim to have had success, with one or two who haven’t. Though, if it does work, and Valve find out about this, I guess it won’t be around much longer.
