Team Fortress 2 Icons, in both PNG and ICO formats. Let me know if any of them don't work.
I made a bunch because I know one icon never works for everyone, and I didn't like the other icons I found on DA.
Inspired by the default TF2 Icon, but neon, as everything should be! One icon uses the TF2 default orange/brown, and the others match my Steam Neon Icons [link]
