Apocalypse High

Publisher: Take Talk

Developer: Electronic Entertainment

Summary of Game

In 2035, Neon County, Japan. Overnight, the moon turned blood red, emitting an eerie glow for three days and nights. Most residents became infected with the "Phantom Virus."

The infected showed red eyes and bloodthirsty behavior. Males lost control completely, becoming "Lust Zombies." Some females retained consciousness in early infection and awakened special abilities, allowing them to resist zombies and establish safe zones.

Protagonist Reima, a student at Neon Future High School, is the only known uninfected male. Rescued by a female search team, he's brought to their shelter. They discover that using abilities comes at a cost—each use deepens viral corruption and intensifies desires. At the limit, users enter extreme heat and must balance the virus through hormonal release, or risk mutation or death.

In this crisis, Reima becomes vital to their survival—a temporary remedy after ability use. Survivors explore surrounding areas, building safe zones while searching for a cure.

FAQs: Installing Games with SideStore

What is SideStore?
SideStore is an alternative sideloading tool for iOS. Unlike AltStore, SideStore doesn’t require AltServer to be running on your computer all the time — once it’s paired, you can install apps directly from your iPhone or iPad over Wi-Fi.
Why do I need AltServer to install SideStore?
AltServer is required for the initial installation of SideStore because it’s the only way to sideload apps onto iOS devices without jailbreaking. Once SideStore is installed and paired with your computer (using a pairing file), you no longer need AltServer, SideStore can refresh and install apps directly on your iPhone or iPad over Wi-Fi.
What is a pairing file, and why do I need it?
A pairing file is a small file that links your iPhone/iPad with your computer. It’s required so SideStore can refresh apps over Wi-Fi without needing to plug in every time.
Why do I need LocalDevVPN?
SideStore uses a specially designed VPN (LocalDevVPN) to “trick” iOS into allowing apps signed with your personal development certificate to be installed and refreshed. The VPN doesn’t route your internet traffic, it only handles the signing and refreshing process.
Will the VPN track my activity?
No. The VPN profile used by SideStore (LocalDevVPN) does not monitor or route your internet traffic. It only exists to allow SideStore to install and refresh your sideloaded apps.
I get an error saying “Untrusted Developer”. What should I do?
On your iPhone or iPad, go to Settings > General > VPN & Device Management, tap your Apple ID under Developer App, and select Trust.
How do I get the pairing file?
You’ll need to use idevice pair (a helper tool on your computer) to generate the pairing file. Once created, you can import it into SideStore on your iOS device.
Do I need to re-pair every week?
No. You only need to generate and import a pairing file once, unless you reset your device or reinstall SideStore.
Do I still need a computer after setup?
Only for the initial pairing and installation of SideStore. After that, you can install and refresh apps directly from your device over Wi-Fi.
Why do I need to enter my Apple ID?
Apple requires apps to be signed with an Apple ID before they can run on iOS. SideStore uses your Apple ID only for signing, it is not shared or stored by SideStore.
My app expired after 7 days. Why?
Free Apple IDs require apps to be refreshed every 7 days. SideStore makes this easier by allowing you to refresh apps directly from your device without reconnecting to a computer.
Is the SideStore safe?
Yes. The SideStore (and AltServer) are trusted open-source tools. They do not pose any harm to your devices, and are only meant to enable the installation of apps on your iPhone or iPad.

FAQs: Installing Games with AltStore

What is AltStore?
The AltStore is a third-party app that enables non-jailbroken iOS devices the ability to install apps manually, through a process known as Sideloading. It gives you a way to install apps that are not available in the official app store, giving you access to games that usually are not supported in the store, like Nutaku’s NSFW games.
Do I need a computer every time I install a game?
No. You only need your computer for the initial setup. After that, you can install and update games directly from the AltStore app on your iOS device.
Why do I need to enter my Apple ID?
Apple requires apps to be signed with an Apple ID before they can be installed. Your Apple ID is used only for signing purposes, and it is not shared or stored by us or the AltServer.
I get an error saying “Untrusted Developer.” What should I do?
On your iPhone or iPad, go to Settings > General > VPN & Device Management, tap your Apple ID under Developer App, and select Trust.
My game stopped working after 7 days. What happened?
With a free Apple ID, apps must be refreshed every 7 days in order to continue using them. Just connect your device to your computer and refresh the app through the AltStore. If you use a paid Apple Developer account, apps instead last for 1 year before needing to be refreshed.
Why isn’t my device showing up in AltServer?
Make sure your iPhone/iPad is connected with an USB cable, and then make sure it’s not in the lock screen. If you are using a Windows computer you will also need to install iTunes and iCloud. Note that they must be downloaded from Apple’s website, they will not work with other versions (such as the Microsoft’s Store version).
Do I need iTunes and iCloud?
- Windows users: Yes. AltServer requires both iTunes and iCloud to be able to communicate with your iOS device. Be sure to download them from Apple’s official website (not the Microsoft Store) to prevent compatibility issues.
- Mac users: No. macOS should already include the necessary software and components, so you don’t need to install iTunes or iCloud separately.
AltServer says “Installation failed.” How do I fix it?
This usually happens if:
- iTunes/iCloud aren’t installed or updated.
- Your Apple ID password was entered incorrectly.
- Your iPhone/iPad is locked during installation.
- Your developer profile wasn’t trusted (see Untrusted Developer fix above)
Can I remove or change the Apple ID saved in AltServer?
Yes. Open AltServer, go to Preferences > Apple IDs, select the account, and choose Remove. You can add a different Apple ID if needed.
Is the AltStore safe?
Yes. The AltStore (and AltServer) are trusted open-source tools. They do not pose any harm to your devices, and are only meant to enable the installation of apps on your iPhone or iPad.

FAQs: Installing Games with Sideloadly

What is Sideloadly?
Sideloadly is a software for Windows and macOS that installs (.IPA) files onto your iPhone or iPad without using the App Store.
Do I need a computer every time I install a game?
Yes. Sideloadly requires a Mac or Windows computer each time you sideload an app.
Do I need iTunes and iCloud?
- Windows users: Yes. Sideloadly requires both iTunes and iCloud to be able to communicate with your iOS device. Be sure to download them from Apple’s official website (not the Microsoft Store) to prevent compatibility issues.
- Mac users: No. macOS should already include the necessary software and components, so you don’t need to install iTunes or iCloud separately.
Why do I need to enter my Apple ID?
Apple requires apps to be signed with an Apple ID before they can be installed. Your Apple ID is used only for signing purposes, and it is not shared or stored by us or the AltServer.
My Apple ID uses two-factor authentication (2FA). What should I do?
You’ll need to generate an App-Specific Password from your Apple ID account page and use that in Sideloadly. For more information, please refer to this guide.
I get an error saying “Untrusted Developer.” What should I do?
On your iPhone or iPad, go to Settings > General > VPN & Device Management, tap your Apple ID under Developer App, and select Trust.
My game stopped working after 7 days. What happened?
With a free Apple ID, apps must be refreshed every 7 days in order to continue using them. Just connect your device to your computer and refresh the app through the SideLoadly. If you use a paid Apple Developer account, apps instead last for 1 year before needing to be refreshed.
Can I install multiple games with Sideloadly?
Yes, but free Apple IDs allow a maximum of 3 active sideloaded apps at a time.
Sideloadly says “Device not detected.”
Make sure your iPhone/iPad is connected with a USB cable, unlocked, and that iTunes/iCloud are installed (Windows only). Try another USB port or cable if needed.
Sideloadly is stuck on “Waiting for device.”
Unlock your iPhone/iPad and keep it connected. If it still doesn’t work, restart both your device and your computer, then try again.
My app won’t open after installing.
Check if you trusted the developer (see “Untrusted Developer” above). If trusted and it still doesn’t work, delete the app and reinstall with Sideloadly.
Is sideloading with Sideloadly safe?
Yes. Sideloadly is a trusted software that does not collect any of your information. It does not pose any harm to your devices, and is only meant to enable the installation of apps on your iPhone or iPad.
