ValveTime Weekly News Round-Up - 13th January 2013

[Omnomnick]

This week saw the arrival of CES 2013, and Valve were there in force as the first SteamBox was revealed by Xi3. We also received a lot of other news this week, such as the arrival of Medusa in a Dota 2 update, the retiring of the nine original Team Fortress 2 hats and a version of the Half-Life alpha was leaked onto the internet. Oh, and we found some Half-Life 2: Episode Four screenshots, which we think you might be interested in.
