Steam News announces a sale on Chivalry: Medieval Warfare, saying the melee combat game is 66% off this weekend. Oddly, they don't mention that this is also a free weekend for the game, and it can be played for free by anyone with a Steam account between now and Sunday afternoon. Here's the pitch for the game: "Chivalry: Medieval Warfare is a first-person slasher with a focus on multi-player. Featuring competitive online combat that seeks to capture the experience of truly being on a medieval battlefield. Inspired from the intensity and epicness of swordfighting movies such as 300, Gladiator and Braveheart, Chivalry: Medieval Warfare aims to bring that experience to the hands of a gamer."
