Whats new

Toplitz Productions proudly announces its cooperation with the Polish development studio Game Island. With their latest title SERUM, the ambitious and experienced team presents a survival-fest in a class of its own. A green liquid, an eerie world and lots of time pressure characterize the fascinating and promising game concept.

"We are delighted to have found a partner in Game Island, who is investing so much heart and soul and creativity in the project, and we are looking forward to the next development steps with great anticipation", explains Matthias Wünsche, CEO Toplitz Productions. "SERUM with its special features fits perfectly into our portfolio and will serve a new, expanded target group alongside Dynasty Games and the Giant Series."

"We are glad that we've found a well-established and trustworthy partner in Toplitz Productions. With their publishing experience, Serum will have a chance to reach a worldwide audience. There has been an excellent understanding between our companies right from our first talk about the game”, says Michal Ojrzynski - CEO Game Island.

The release of SERUM is scheduled for the end of 2023. Until then Toplitz Productions and Game Island will introduce players step-by-step to the mystical world where the green liquid is the most precious commodity and the race against time ensures survival!
