How to Complete Steam Holiday Objectives
Well now that the 2011 Steam Holiday Sale is on, people have been asking me how to complete the objectives. Well I don’t have all the answers, but the Steam community has been hard at work grabbing from the Stream Registry and learning all the games that will have achievements/objectives to complete. Some provide a save file you can load and get the achievement quickly, others are just video guides. Hope this helps you and that you end up winning the Steam Grand Prize: ALL STEAM GAMES!
