- Full Controller Support - Quarantine Zombies - 1 May 2026
Hi everyone!We received tons of complaints about the lack of proper controller support. We did have partial controller support before, but the quality wasn’t good enough for the Stones Games team, and it definitely wasn’t good enough for you, our beloved players.So, we added full gamepad support and completely reworked the interface to make it controller-friendly.And that’s not all. In this update, all refugee voice lines previously generated by AI have been replaced with full voice acting by real actors. The refugees now feel much more alive, even if they are almost dead. Just kidding.As we mentioned before, AI-generated voice acting was only a temporary solution caused by budget limitations. That issue has now been fully resolved.Enjoy the game!
