Need to do something in Team Fortress 2? - action items are there to do the job. They produce an action when players click on them. While some of the action items may have a limited number of uses, others call up the activation menu once they are selected, so you should use these items only in a safe place. You can obtain most of these tools in the Mann Co Store. But if you want to find the best deals of the action TF2 items or sell them to earn money, then visit DMarket.
