About the Game
Prepare yourself for the most thrilling night of your life! Something strange has happened and people everywhere are turning into blood thirsty walking corpses. But guess who’s the brains behind this hungry undead army? YOU! So spread this pandemic to wipe humanity off this planet. Because the only way to survive the zombie apocalypse, is to BE the apocalypse!
But the brainless undead are quite dumb… even dumber than you might expect given their lack of grey matter. Because when left to their own devises, they will just endlessly walk forward and fall into permanently deadly booby traps placed by not-so-helpless humans. So to accomplish your mission of world extermination, you will need to help guide them to their next yummy meal. Luckily you can utilize numerous special mutations to make your troops evolve and fulfil their appetite for flesh. But beware! Humans will not facilitate your dark will….they will fight to survive.
Spread terror through 50 levels and enrol more zombies into your undead army. Along the way you’ll have to solve brain tingling puzzles, and fight increasingly powerful foes that are hell-bent on staying alive. The closer you get to total world extinction, the harder survivors will fight to put you in the ground….for good.
Blood, tears, non-sexual moans, inappropriate laughter, and tons of puzzles that will literally blow your brains out... This is Zombie Night Terror!
- Command a Zombie Horde: You are the brain, they are the muscles. Your zombie horde will obey your commands without any strike risk or complaints … On the downside; you can’t have any heated conversations about late night movies or cool books anymore tough!
- Unique Mutation System: Having an army of deadly zombies is awesome. Having an army of mutated zombies is way better! Take advantage of our mutation system to overcome the enemy’s defences, by creating powerful new zombie types. Each has their unique power and abilities that can help you overcome different situations.
- Combo System: Because you thought mutations were your only way to facilitate your meat feast, we spiced it up allowing you to combine those and see what your enemies are made of (literally). Let’s show those pesky humans how to have fun!
- Level Editor With Full Steam Workshop Support: Ever wanted to create your very own devious Zombie Apocalypse? Then we do have something for you! The Level Editor lets you design levels from scratch and share them with the community, using Steam Workshop. Start slow by crafting a single level, then crank things up with a full chapter loaded with enemies, traps, bonuses, mutations, and intellectually superior dialogue of your own choosing, all of which unfolds according to your devious plan.
- You are not alone: Having zombies is kind of like having a pet; it’s fun but you need to take care of them… That’s what humans are for, as they are the perfect way to keep your zombies well fed and busy. But beware! Humans are well armed and they do not appreciate the toothy company of the undead.
- Contaminate: Don’t have enough company? Do you need a bigger horde? Well, just convert Humans to your cause then! You don’t necessary need to bring flowers and be charming, as a single bite right into the neck (or anywhere that pleases you) should be enough to do the trick!
- Destructible Environments: In times of a zombie apocalypse, humans love to take their time playing hide and seek. However when the hunger for tasty flesh is this painful, you don’t have time for such childishness. So use the power or your horde to destroy their playground and spread terror among them… PEEKABOOM!

Due to a engine bug, there was a bug in particle collisions making the game crash in some conditions, it was especially visible when exploding zombies.
We've updated the game to a more recent version of Unity that should fix this issue.
Unfortunately, the latest version of Unity with this fix is not compatible with 32 bits versions Linux. So, if you are still using one of those, you'll have to keep using the Legacy version version of the game.
Let us know if the crash is still happening on this bug thread.
Thanks for your support and sorry for the inconvenience.
