CD Projekt has released a video dev diary for The Witcher: Versus, a completely free-of-charge web-browser game formerly known as The Witcher: DuelMail and based on The Witcher. The Witcher: Versus centers around battles between two players using one of the three completely different character classes. You'll gain experience as you continue to win and this allows you to advance to higher levels of character development, along with gaining new skills and items to use in your battles. The game requires only a PC with an internet connection and a web browser with Flash installed.
