What is Valkyrie Crusade?

[SinicalGeek]

Valkyrie Crusade (jp.:神界のヴァルキリー) is a Card Collection Game (CCG).

The main goal of the game is to collect and evolve different kinds of cards which you use to either fight against other players or go into the campaign mode to conquer different areas and fight against archwitches. End-level play involves competing in the leaderboard rankings for unique and exclusive rewards.

Another feature of the game is the ability to build your own city inside your kingdom. You can upgrade important and useful facilities by spending resources on it. Building/Upgrading any facility takes time. In fact, the game is based in real-time, meaning that every minute that passes in real life is a minute passed in the game.
