Hello, Checkpoint Operators!

Since our initial release we have been hard at work to deliver an improved version of the game. It has taken us a while and we are very proud to finally roll out our biggest yet update to Quarantine Zombies: Contamination.

Contamination brings a meaningful set of improvements to the game. We have been listening to your feedback, and this update focuses on expanding the game mechanics, making the gameplay smoother and overall gives the game more of its own identity.

Here’s what you will find inside:

  • New melee combat system;

  •  More than five new symptoms;

  • Three new tools to interact with the new symptoms;

  • There is an all new progression system;

  • Added new shooting QTE mechanics;

  •  Reworked the car’s physics - it should now be easier to navigate it through Chicago;

  • We have added more than 100 new survivors and 10 new zombie variations;

  •  We also removed AI voiceovers from the game and replaced them with genuine voice acting;

  • Added full gamepad support;

  • Added Steam Deck support - You can now play Quarantine Zombies on the go;

  • More than 150 bugs were mercilessly liquidated;

  • We have worked hard on a variety of optimizations that resulted in an average 50% improvement to performance.

A huge thank you to everyone who has supported the game and shared feedback. We hope you enjoy playing the new and improved version of Quarantine Zombies and we would love to hear what you think about it. Quarantine Zombies: Contamination is a free update that is available now and free of charge.

See you in Chicago!
