We want you to enjoy your experience on Steam so we added many things to the game to make it special to the Steam Community. There are currently 27 achievements in-game and you will unlock them in Steam as well. In case a problem happens or you unlock the achievement while offline, you can visit the Awards Room when you are online again and claim your earned Steam Achievements. We also added 9 Trading Cards for you to collect given in short periods of time. With these you can craft a full set into badges and get any of the 3 bonus profile backgrounds and 5 emoticons (more soon!).
