Elon Musk just gave shares in Poland’s biggest computer game maker a turbo boost, by enthusing over CD Projekt SA’s Cyberpunk game on his Twitter account.

The company’s stock soared as much as 19%, the most since June 2015 and with trading volume nearly six times its three-month average, after the Tesla Inc. chief executive officer tweeted Thursday that “the esthetics of Cyberpunk are incredible.” Hours earlier, the billionaire had tweeted that it would be possible to play the complex and futuristic game on Tesla’s new Model S Plaid.
