You can find a complete Kiss Psycho Circus walkthrough on IGN, which covers each realm and its secrets ^[1]. The game is a first-person shooter where each stage follows the same pattern, so once you learn one, the rest feel familiar ^[2].

IGN's guide is laid out realm by realm, so you can jump straight to the area you are stuck in. Each realm has its own section, and the guide also helps with specific bosses and hidden items. If you are hunting for something like a secret in Waste Wharfs, you can go straight to that part of the page ^[1].

Keep the guide open in a second window or on your phone while you play. The walkthrough marks secrets with a key symbol, so you will know which areas to explore more carefully. Watching for those marks is the easiest way to collect everything without backtracking through the whole game ^[1].

Key takeaways

IGN's walkthrough covers every realm and its secrets ^[1].
Each stage in this first-person shooter follows the same pattern ^[2].
Keep the guide open while you play so you can spot the key-marked secrets.

How is the game laid out?

Your elder choice at the start decides which path you take, and the Nightmare Realm stays locked until you finish the game. IGN's walkthrough says that if you have made it through to the end, you can choose the Nightmare Realm ^[1].

At the start, the walkthrough asks you to select your elder ^[1]. Pick one, and work through the realms from there. Save the Nightmare Realm for a later playthrough, once you have reached the ending.

Watch for the key symbol

IGN marks secrets with a key symbol, so keep the guide open while you play ^[1]. When the walkthrough flags an area that way, slow down and search it fully. Doing that as you go is much easier than backtracking later.

For example, if the guide flags a key in a realm you think you have cleared, go back and look around before moving on.

Pick a difficulty that fits

Difficulty changes which walkthrough fits your run. StrategyWiki has a walkthrough that describes how the game is played on the highest difficulty setting, so it suits players who want that challenge ^[3].

If you are playing on a lower setting, a realm-by-realm guide with marked secrets will likely serve you better. Match the guide to the setting you chose, so you do not follow steps that do not apply to your game.

How do you get the game running on Windows 10 or 11?

The ReLaunched Edition is the version to get. It is a re-release of the 2000 game and is compatible with Windows 10 and Windows 11 ^[4]. Install it first, then use Windows' Compatibility Administrator to set up its files.

Install the ReLaunched Edition.
Open Windows search and search for Compatibility Administrator (32-bit). Open the tool when it appears ^[5].
In Compatibility Administrator, go to System Database (32-bit)>Applications>KISS ^[5].
Under Applications, find KISS Psycho Circus: The Nightmare Child ^[6].
In the right pane, find client.exe and psycho.exe ^[6].

The menu path has three levels, so open each one in order before you look for the files. Each level narrows the list until the game's entries appear in the right pane.

Once both files show in the right pane, you have reached the entries this setup needs. From there, you can close the tool and launch the game.

Which walkthrough should you follow?

Choose your walkthrough based on how you want to play. A realm-by-realm guide suits players who want every secret, and a highest-difficulty guide suits players on the hardest setting. GameFAQs offers a third option.

Realm-by-realm for every secret

Use a realm-by-realm walkthrough if you want to find every secret while you progress. IGN's walkthrough gives the complete route for each realm, so you can read the section for the realm you are in and keep moving. ^[1]

If you are stuck on a secret in Waste Wharfs or on the fight with Fortunado, the same guide covers both. You do not need to read ahead to find the help you need. ^[1]

Highest difficulty

Use a highest-difficulty walkthrough if you are playing on the hardest setting. StrategyWiki's walkthrough describes how the game is played on the highest difficulty setting, so its steps match the harder version you are playing. ^[3]

This is the better choice if a normal-difficulty guide makes the game feel too easy to follow. You get the route that fits the challenge you picked.

Another option

GameFAQs has a guide by DEngel, last updated 03/24/2024, as another option. ^[7] It is a useful second guide if you want to compare how two authors handle the same realm.

What should you do next?

Start with your elder, then work toward the Nightmare Realm after you finish the game. The guide begins with selecting your elder, and it points you to the Nightmare Realm only once you have made it through to the end ^[1].

Pick a walkthrough that matches your difficulty and the realm you are on. The guide covers each realm, including the fight against Fortunado and the secrets in Waste Wharfs ^[1]. If you are stuck in one of those spots, jump to that realm's section instead of reading from the start.

The one thing to remember is that your elder comes first and the Nightmare Realm comes last. Open the walkthrough, select your elder, and start your first realm tonight.
