'Call of Knights' is an RPG card pixel art game created by Olive Panda Studio. It features two gameplay and content sections: 'Song of Knights' and 'Chapter of Stars.'

'Song of Knights':
Adapted from Nobel Prize-winning author Henrik Hertz's 'The Knights of the Cross,' the main gameplay involves card-based RPG role-playing. The game integrates a partner skill combo system into card battles, releasing unique skills based on the cards played by the player, creating different styles. Players will also recruit numerous companions and embark on an epic journey.

'Shining Stars':
Set in a magical continent called Antana with six culturally diverse nations, players take on the role of a young lord from one of the kingdoms. As the demon realm threatens to invade the continent, players must travel far and wide to find companions for their knightly order, establish their own knightly order, embark on adventures, strengthen their abilities, and defend the human frontlines.
