Sega opened a teaser website on Monday revealing that it will announce a new "Valkyria Project" on November 20 at 12:00 p.m. JST (10:00 p.m. EST on November 19).

Sega released the first Valkyria Chronicles game on the PlayStation 3 in Japan, Europe, and North America in 2008, and released Valkyria Chronicles II on the PlayStation Portable in 2010. Sega also released Valkyria Chronicles III on the PSP in 2011, but did not release it in the West. Sega released Valkyria Chronicles on the PC in November 2014, and released a similar remastered version for the PlayStation 4 last year.

The first game in the series inspired a 26-episode television anime series by A-1 Pictures in 2009. The third game inspired a two-episode original video animation in 2011.

Sega released a new game titled Valkyria Revolution for the PlayStation 4 and PlayStation Vita on January 19, and released it in the West in June with an additional Xbox One version. The game is set in a different world from the main series.
