For any of you who have Steam and a copy of any source game such as Half-Life 2 should really check out this free mod called Age of Chivalry. I' ve just recently played it and I have to tell you its a lot of fun, most satisfying are the decapitations and acting like a knight from the middle ages yelling in the microphone "COME!!!COME HITHER FOR I SHALL SPEAR THEE WITH THY SWORD!!!!"
I recommend playing with friends, you can add me as a friend via steam, my name is FoxHound...
