Half Life (and it's babies HL2, all the episodes, etc) found a place in our home many many years ago. A couple of years ago Valve (creator) and Steam (online game client) created the Orange Box, a collection of many of their games all in one box. Steam allows users who have the game to go online and share their stats and play with other people from around the world. Not only can we LAN from computer to computer and play but also with family members in other states. (With them having their own game and key, of course.) We've been die-hard fans for years!
This hat is strictly fan art from folks that admire the games. If you are considering purchase, please be aware that it is in no way a licensed product. I have no affiliation with Steam or Valve whatsoever.
