CD Projekt RED has announced the upcoming closed beta of The Witcher: Duel Mail closed. Based on the company’s PC role-playing game, The Witcher, The Witcher: Duel Mail is a free-of-charge Web browser game. The start of open beta is planned for April 7, with the final version scheduled for release on May 9.

The Witcher: Duel Mail is centered on battles between two players digitally incarnated as one of three different character classes. Winning consecutive fights against other real-world people gains the player experience, which allows him to advance to higher levels of character development. Players queue up attacks, magical spells and defensive maneuvers, then send their challenges to other players, who must create their own countersequence in hopes of being the last one standing. In order to join, the game requires only a PC with an Internet connection and a Web browser with Flash installed. Besides fighting for the top spot on the game’s ladders, top players can also expect to collect rewards in battle. To avoid feeling rampant loneliness, players can invite friends via e-mail in order to play together.
