Game Muse Interview
The Intruder is a survival horror game where you go prepare yourself for the imminent, inescapible encounter with the eponymous Intruder. It will take longer if necessary, but right now it's targeted towards a 2013 release.


You play as yourself after a horrifying encounter with an unknown entity. Your memory is greatly impaired, and you don't know what happened or where your things are. The only thing you remember clearly, is that it will return.


As the game's concludes, the strain on your memory is so great that you don't even remember where around the house you left your items. You will have to go and look for them, aided by vague memories, with the Intruder bound to catch up with you any second now.

You spend most of the game preparing yourself for that inescapable encounter, while trying to prevent running in to it early. You have several in-game days to explore the surrounding areas, look for weapons, ammunition and tools. You can even barricade your house to buy yourself some more time.

You'll also need to eat and sleep every once in a while, to stay healthy and energetic. After all, you may have to run real fast at unexpected times. How far you go with all this is up to you. Is it worth looking for a gun, or would the axe in your backyard suffice to defend yourself? Would two bullets be enough to kill it? Would boarding the windows and locking the doors buy you enough time?
Is five hours of sleep enough, or does that slow you down too much? How long can you refrain from going back home to eat, before you actually start feeling unwell?

These are all things you have to think about. It's all about making sacrifices. Careless decisions will leave you unprepared when the time comes.

Key features (* means already functional):
  • Advanced AI: procedural animation, a procedural model and simulated goals and emotions*

  • Continuous Time The time remains consistent between maps. 1 real second = 1 in-game minute*

  • Non-linearity: Small free-roaming world where you can discover set pieces at any time, in any order, or skip them entirely*

  • Interaction System: Open drawers, cupboards and doors by using your mouse.

  • Barricading: Board up windows and barricading doors to protect your home*

  • Intruder Placement System: A system that decides when and where the Intruder shows up*

  • Memory system: Press R to close your eyes and try to regain useful memories.

  • Finale Event: Found items are randomly hidden in your house, and you have to look for them before the Intruder gets to you.*

  • Survival System: You have to eat and sleep every once in a while, or you will be slower and more vulnerable.*

  • Dynamic day/night cycle: If you don't pay attention, you might find yourself alone outside. In complete darkness.

  • Diverse Weapons: Multiple weapons with distinct qualities and difficulty to obtain.

  • Non-essential items: Several types of useful items that are not mandatory to collect.

  • Decent mod capabilities: This game could work with a completely different theme/setting, and I'm going to keep support of that in mind while developing the game.

Minimum System Requirements

The following System Requirements are an estimation based on the most recently released game on the same engine, Counter-Strike: Global Offensive. They are subject to change.

OS: Windows® 7/Vista/XP
Processor: Intel® Core™ 2 Duo E6600 or AMD Phenom™ X3 8750 processor or better
Memory: 1GB XP / 2GB Vista
Hard Disk Space: Probably several Gigabytes. Most likely somewhere between 1 and 5.
Video Card: Video card must be 256 MB or more and should be a DirectX 9-compatible with support for Pixel Shader 3.0

Current Status

As you can tell, most of the core features are already functional. Right now I need to know if people like this concept, and want it to be on Steam when it's finished.

About this page.

Besides showcasing the game, this page is also for two-way feedback. If you have questions or ideas about the game you can leave a comment below and I'll take a look at it.

There's a lot of comments right now, so it's likely that I'm not able to answer all questions. I'll try to at least read of all of them (GabeN style).

Very specific things, like what weapons there are in the game, might remain a secret until the game's release. They might be more fun to you discover while playing, or they might be heavily subject to change. I'll gladly discuss the larger ideas and game mechanics.


Steam Greenlight sounds like an excellent way to funnel the potential future community members into one place, and talk to them all at once. I intend to harness that. I will try to figure out what people like, and what they don't, and change the game accordingly.

Please keep this in mind while deciding to upvote or downvote. If you don't like something, tell me. There's a large chance that the thing that's bothering you right now will be much better at release.


Right now it seems like I'll be able to finish this all by my own, but if the sheer volume of content proves unwieldy, or the game grows significantly larger, I might look for people to help develop this game in the future.

If I ever do need assistance, and you want to be considered, e-mail some examples of earlier work to:

The people I'd most likely need are voice actors, modellers, texture artists or audio wizards.

Please remember to show examples of your earlier work. Especially if you're a voice actor.

I've been following this ambitious project since the day it was posted on Greenlight, and I'll have you know that with the revelation that development has ceased, I am furious. The day you uploaded this artist masterpiece was the day my life truly changed forever, I have been hyped down to the bones since I thumbed this project up. You have disappointed us, Mister Royzo, the community. You will never have a job in the games industry again you pathetic little clod, you may call me entitled but I will have you know that I am simply stating the facts. There will be repercussions for your actions, mark my word, boy.

Sincerely, the community.

It's very safe to assume that this is abandonware. It's been sitting here since late 2012 with no updates of any kind.

God damnit, don't hide behind a damn mask! Tell us if it's canceled or not! At least we won't be held in infinite suspension.
