GDANSK (Reuters) - Poland's biggest video game maker CD Projekt ( OTGLF ) on Friday released a trailer for its planned new game in the blockbuster "Witcher" fantasy series.

After the troubled release of its previous big-ticket game "Cyberpunk", CD Projekt ( OTGLF ) has been careful not to indicate when "The Witcher IV", currently in the full-scale production phase, will premiere.

The single-player role-playing game is a successor to "The Witcher 3: Wild Hunt", expanding the universe of the medieval fantasy franchise which has sold more than 75 million copies since the first game was released in 2007.

"The Witcher IV aims to be the most immersive and ambitious open-world Witcher game to date," CD Projekt ( OTGLF ) said in a statement.

The game is led by Ciri, the adopted daughter of Geralt of Rivia, the main character from the previous Witcher games.

Analysts expect it to debut in 2026 or 2027, leaving CD Projekt ( OTGLF ) without a major earnings driver until then.

The game is being developed using customised Unreal Engine 5 technology, which also powered the six-minute trailer.

Erste Group analyst Piotr Bogusz said the trailer can show the target quality of the game.

"Interest in the trailer is relatively high, and the trailer itself is rated mostly positively."
