It seems Valve has not forgotten Team Fortress 2 exists and a fresh update is out now, which pulls in some new security measures and the Summer 2021 Cosmetic Case.
Along with Counter-Strike: Global Offensive seeing it's 10th operation with Operation Broken Fang, Valve's other popular first-person shooter Team Fortress 2 is doing a new Smissmas 2020 event.
Valve have realised again that Team Fortress 2 is actually still online and have done a fresh update, although only minor it does add in a new Summer 2020 Cosmetic Case.
Team Fortress 2 Classic is the re-imagining of the 2008-2009 era of the original Team Fortress 2 designed as a casual mod that anyone can get into and enjoy a little FPS action.
