Discounts
Every price cut of more than 20% we have observed, in each market that quoted one, with this game's chart position on either side of it. These are episodes, not a model: a sale is one event, and one event cannot tell you what the next one will do.
Reviews, worldwide (the counter carries no country): 0/day in the week to Aug 29 → 0/day in the week after.
For scale, across Steam · Top Sellers · Brazil over the last 30 days: the 26 chart moves that followed a price cut of more than 20% went a median of 7 places towards #1, and the 2,400 moves with no price cut behind them went 2 away. One store, one chart, one country — it is the only place we have enough observations to say even that.
Prices outside the United States have been collected since 6 August 2026 and chart positions since 19 July 2026, so a cut older than that has no market to compare and a market that joined later has no history yet. Nothing here is converted between currencies.
About
This is not a simulation. This is a biological warfare laboratory.
Develop bio-weapons by manipulating DNA in your own lab. Synthesize synthetic bases, design custom DNA sequences, engineer lethal viruses, and prepare them in injectable form to unleash upon the world. Every failure brings you closer to a stronger variant.
Utilize your collection of natural and synthetic bases to create diverse effects. Strategically combine properties such as toxicity, mutation potential, spread rate, and tissue-targeting effects.
Order components from the deep web, receive them at your lab, and craft your own bases by mixing the correct proportions. Crafting requires knowledge, not just ingredients.
Create custom DNA strands of up to 100 bases. Decide which base goes where and when to modify it—your choices determine the fate of the virus.
Manage the entire process—from synthesis to purification, replication, and preparation for injection—with a single, real-world-inspired device.
Design an effective vaccine against your own virus. Inactivate the virus with heat, strengthen it with adjuvants, formulate, and test.
Deep systems grounded in synthetic biology, molecular genetics, and virology.
Simulate the behaviors of your custom-designed viruses.
Simplified but coherent representations of synthesis, PCR, purification, and injection steps

[b]Get ready, world, my mutants will be the strongest![/b] In this game, we create our own crazy virus to infect all of humanity. It sounds villainous, but it's a lot of fun. We test samples, make sure the zombies don't escape and kill us, and step by step get closer to our goal. An interesting concept and nice execution.

The game is way more complex than it looks at first. Creating viruses experimenting with DNA and trying not to accidentally ruin everything is actually really addictive. I like that the game tries to build its mechanics around real science instead of just random arcade gameplay. There is a lot to experiment with and it genuinely feels rewarding when a new creation finally works the way you wanted.

I’ve been playing for some hours and I found it really fun to play, it has a really deep gameplay and create your own bio weapons keeps you interested. The game runs perfectly in my pc, I have encountered some bugs but with the latest patch now works perfectly.
If you enjoy scientific simulations, methodical experiments, and the systems that emerge, this is perfect for you. I didn't even realize how time flew by while trial and error and trying to do better again and again. I highly recommend it.
What was clunky in the demo was fixed on the release, trying to speedrun to make world infected seems like a perfect fun for the game. For a simulator game it is good to chill and pass time.
First of all: I am a friend of the developer, but I bought the game by myself - no key or game was giftet, so it's my honest review about Dead 4 Now: Bio-Weapon Simulator. Second, I love this game. It's super fun to produce some kind of viruses to destroy the world. Sometimes I failed and my corpses explode, sometimes it works and I infected the world more and more and sometimes hell breaks loose and my test subject tries to kill me. It's something that really stoods out for me and I really enjoy my time in this game. The graphic is good so far. Nothing fancy and I would love to see some kind of DayZ-Shader to make it more "darken". But at the end, it's absolutely functional and you get the feeling to work in a super clear lab (what I would expected in Real-Life too). The gameplay loop is super fun and I can't wait to get deeper into the game, create some special viruses and destroy the whole world. The developer did an great job in my opinion and I love the fact that he is updating his game continously. My final conclusion: Currently I am rating it a very good 7.5 out of 10 and if you're into such kind of games, try the demo and decide to support this little gem or not. Personally, I am glad that I've bought this game. It's really worth it in my opinion.
Overall, the game is truly unique in its own way. It feels like Plague Inc, except here you personally create the virus yourself in order to infect the entire world. The virus creation mechanics are interesting and very complex - even with the ingame guide, I managed to create my second virus only after 20-40 attempts. If the game hadn’t given you the first virus and the ability to sell test subjects at the auction, the scientist’s evil plan would’ve failed at the money grind stage xdd After struggling quite a bit, I finally infected the whole world and somehow managed to cure myself too. Overall, I’m satisfied with the game, but there are some downsides. 1) Constantly carrying chemicals to the printer is tedious. Until you get workers, you have to carry boxes one by one. Why not make it possible to carry at least several boxes at once? 2) Backstory and plot — the game seriously lacks them. At least some kind of introduction to the main character’s story would help: why is he infected, and why did he decide to infect the world? 3)Tutorial — creating a virus felt like a lottery. I managed to create one mostly through sheer luck. Overall: the game has huge potential. It just needs more story and world-building, because everyone is interested in learning the backstory. Why is he breeding zombies in the first place?
Overall I think this game is good. Requires a bit of a learning curve and it definitely has some improvements that can be made but with the developers being as active as they are in multiple mediums, I have no doubt they will be made. They are fast to respond to feedback. Apparently this is the first of three games being made that will interconnect with the others being multi-player.
This is a really cool idea. I've always wanted to try my hand at being a lab technician, and this is the perfect opportunity. Experiment while creating.
