Sega's latest take on the Valkyria Chronicles series is a browser game. View the first trailer for Valkyria Chronicles Duel here.
According to the trailer, Duel has players build up battalion by collecting cards. You'll find over 200 character cards in all.
Your duties include developing your base camp, taking control of enemy territories, acquiring new troops by becoming a commander, and taking part in "3D character battles" featuring the same basic style as in the Valkyria Chronicle games.
As with most browser games, Valkyria Chronicles Duel is free to play, with item transactions.
You'll find the game's official site here. A user test is running from today through June 25.
In addition to the browser-based game, the official site mentions a "smartphone app" of some form, but it's not clear what this is at present.
