The "Cube Experimental" is a Mod for Fallout 3. Just started as a small test project to find out the possibilities of the Fallout-3-Engine and growth larger now. This project places a hidden entrance, of an forgotten cube complex, to the wasteland of Washington D. C.. To explore it, you only need your current Fallout 3 character.

WARNING! Systemtime runs out in: (on May 8th)

Some data/features

  • 65000+ objects
  • 500+ scripts
  • 13 level
  • full voice acting
  • collectable bonus stuff
  • sounds banal, but we have full usable ladders, what the engine normally not supports.
  • 1 big quest - a confusing time

Neotorious made an video how to get in:

Walkthrough (German Version)

Translated Versions
SureAI is currently working on an full translated English version of the Cube Experimental. The French translation by Doezer and his team will start after the release of the English version.

If you have problems with the terminals ingame, nordmarv found a way: "At beginning I had the terminals bug (no option to open doors) but I moved the cube.esm and now works. I put it just down the fallout.esm in FOMM list."

Just a question; How does this work?

Will it work like the DLC and just be added into the normal game somewhere for you to find it? Or do you have to enter a console command or some **** like that to play?

I just played the mod through for the second time and wanted to (again) tell you how much i loved it. The first time i played it, it had just come out and was only in German. I was so excited to play it i played it in German and while some of it didn't make sense (mostly because i don't speak German), it was still one of the best mods i'd ever played. Now that i can understand the dialogue, it officially IS the best mod i have ever played.
Thanks again for the great mod!

Now...what could I say that does this mod justice? Well, it has to be played to be believed to the point thatr it beats anything Bethesda has produced (I still love 'em). I found the storyline enthralling, the puzzles brain taxing, the terror unbeleivable and I sure as hell didn't come out feeling unrewarded (the house and weapons).

Loved it. I guess you guys are a big fan of Portal and Half-Life.
I'm wondering - have you ever read the novel or seen the movie 1408? Because that one part when SPOILER SPOILER SPOILER ((when you think you're out but in fact you're still in the hypercube)) ALRIGHT SPOILER END really reminded me of that. The main character thinks he's been out of the cursed room 1408 for weeks, but eventually, while he (seems to be) in the post office, the construction workers, who are there to fix a door or something, start visciously taking down the walls and reveal that behind the plaster and the brick is the wallpaper of room 1408. The world starts spinning for his eyes and when it stops turning he's all alone in room 1408, and a swift look at the clock reveals that just a few minutes have passed since he first entered it. This leads to him clenching is hands around his head and shrieking "I WAS OUT! I WAS OUT! I WAS OUT!" a few times.
Well, that was kind of my reaction upon finding out I had never left the hypercube.
Great work, once again! Are you people going to continue modding?

I liked this mod. When u beat it, you get a house in the facility.If you find the elevator that goes to your new home, a panel on the right side has (i think) 6 tags. For people who cant find all tags, type in the console "player.showinventory" without "" and find the tags name and the id numbers. Then player.additem "id name" x x= Number u want.

So, what is this really about. The movie cube? Cause this looks like a great mod, is it a horror mod?

Just got to read xD I might give it a try.
