About Plague Inc: Scenario Creator

I’m a retiree, not a tech wizard, but I do love my strategy games on my Google Pixel 7. I’ve been playing the main Plague Inc game for years, and when I saw this Scenario Creator app for a few bucks, I thought I’d give it a shot. It’s basically a tool to let you build your own custom disease scenarios from scratch. You tweak the starting country, how fast the disease spreads, what symptoms pop up, and even add in special events. Then you can share your creation with other players or download theirs. I downloaded it about a year ago because the other app I used for custom games kept crashing on me. This one has been stable for me, which is a relief. I’m not the type to spend hours on complex menus, but I found that once I got past the initial confusion, it was pretty satisfying to make my own little plague. My grandkids thought it was cool, too, even though they just wanted to see how fast they could kill everyone.

Core Features

The main thing is you get to control everything. You pick the starting country, like Madagascar (good luck getting out of there), then set the difficulty from easy to impossible. You can choose the disease type: bacteria, virus, fungus, even a prion. I spent a whole Tuesday afternoon just messing with the gene modifiers. These let you adjust how contagious the disease is or how much it mutates. You can also write your own description and name for the scenario. That’s fun if you’re creative, but I mostly just made “Grandpa’s Flu” or something silly. Another big feature is the sharing system. You can upload your scenario to the community library, and other people can rate it and play it. I uploaded one on a rainy Saturday in March, and it got a couple of plays. I felt like a real game designer for a day. The app also has a search function to find scenarios by popularity or newest. There’s no in-app purchases or ads, which I really appreciate because I hate getting nagged to buy gems or coins. It’s just a straight tool for making and playing custom games.

Real-World Use

I mostly use this app in the evenings while sitting on my porch, waiting for the sun to go down. I’m not playing the actual Plague Inc game inside this app; I’m designing a scenario that I then open in the main Plague Inc app. That part confused me at first. You don’t play the game here—you build it. So you create the rules, then save it, then open the main game and load your scenario. It’s a two-step process that took me a few tries to get used to. For example, I wanted to make a scenario where the disease starts in Greenland and is really slow, but governments react super fast. I had to toggle a bunch of sliders and checkboxes. My biggest frustration was the interface. It’s not terrible, but the buttons are small on my Pixel 7, and sometimes I’d tap the wrong thing. My thumb isn’t as precise as it used to be. Also, the community scenarios are hit or miss. I downloaded one that was supposed to be hard, but it had some weird bugs where the game crashed halfway through. Still, for making my own simple scenarios, it works fine. I even showed it to my neighbor Bob, who likes strategy games too, and he made a zombie plague scenario that was pretty clever.

Pricing & Value

It cost me $3.99 when I bought it, and I think that’s fair. There’s no subscriptions, no hidden fees, no ads trying to sell you currency. You pay once and you own it. For a year of use, that’s cheap entertainment. The main Plague Inc game itself costs a couple of bucks too, so together it’s a solid pair. But I’d only recommend this app if you already really like Plague Inc and want to make your own challenges or try weird settings. If you just want to play the base game more, you don’t need this. I’ve gotten dozens of hours out of it total, between my own designs and trying other people’s. So value-wise, it’s a good deal for the right kind of player.

Updates & Support

I haven’t contacted support because I haven’t had any major issues. The app has been stable on my Pixel 7 through several Android updates. I did notice the app got a small update about six months ago that fixed some sharing bugs and added a few new options for symptoms. I check the app store reviews sometimes, and they’re mixed. Some people say the interface is clunky, which I agree with. Others complain that it’s hard to find good scenarios. I haven’t seen the developer respond to any reviews, but the app does get occasional updates, so they’re still working on it. That’s good enough for me. If something broke, I’d probably just wait for a fix rather than call support.

Data & Privacy

It asks for permissions to save files to your device and access the internet to share scenarios. I don’t think it collects much personal data, but I’m not entirely sure. The privacy policy says they only use data to improve the app and don’t sell it. I’m not a privacy expert, but it doesn’t feel creepy. No ads tracking me, no sign-up required. I just downloaded it and started using it. That’s the way I like it. Simple and straightforward.

Frequently asked questions
How do I actually play the scenario I create in Plague Inc: Scenario Creator?

You don't play the scenario inside the Scenario Creator app itself. Instead, you build your custom disease rules, save the scenario, then open the main Plague Inc app and load it from there. It's a two-step process that can be confusing at first, but once you get used to it, it works smoothly.

Can I share my custom scenarios with other players, and how do I find scenarios made by others?

Yes, you can upload your scenario to the community library where other players can rate and play it. To find scenarios, use the search function to browse by popularity or newest uploads. I uploaded one myself and got a few plays, which felt pretty rewarding.

Why does the Scenario Creator app keep crashing or have small buttons on my phone?

If the app is crashing, it's likely a rare issue since it's been stable for most users, including me on my Pixel 7. For small buttons, try zooming in or using a stylus if your phone supports it, as the interface can be tricky for less precise thumbs.

I downloaded a community scenario that seems broken or unbalanced—what can I do?

Community scenarios can be hit or miss in quality. If you find one that's broken, you can rate it low to warn others, or simply delete it and search for more popular or highly-rated scenarios. You can also tweak the scenario yourself if you save a copy and adjust the sliders.

How does Plague Inc: Scenario Creator compare to other custom game builder apps?

Unlike some other custom game apps that crash frequently, this one has been very stable for me. It's also ad-free and has no in-app purchases, so you get a straightforward tool without nagging. The main downside is that you need the main Plague Inc app to play your creations, which adds an extra step.
