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:

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."

Nicholas Breckon, the community manager of Bethesda Softworks, spoke with Dennis from SureAI and Cube Experimental about Cubes, Modding, SureAI and also wanted to know - when is Nehrim coming out? Read the full interview on

I see the only way to win this game (mod) - is not to play. Seriously. It is beautiful, carefully designed, eye- (and ear-) candy. But this is an experiment designed to torture people, and this is what it does.

It has to be greatly inspired (beside The Cube movie) with Halflife. First we go up, and up, and a little higher. Then I press a button... Have you seen "Freeman's mind" episodes? :) "Why do I have to press every button I see?!" :D And then, I almost hear Freeman again: "NO!!! Not down again!!!" xD

The maze is so insanely frustrating, I couldn't pass through it even with "tcl" cheat. The room with all those mines and beams - I hate it! I hate the idea in all games I've seen it.

I think "Cube Experimental mod" is more than a mod or even a computer game. It's a real experiment on people to test how masochistic they can be :)

Aiming at this - this mod is perfect. For me, the mod could be way better if it had way more puzzles than a maze and running (and jumping) in circles. The maze would be cool if it was a little smaller and easier. Computers and switches could be used to create lots of logical puzzles. Turrets and robots should be hacked, not fought. If I designed this mod, I'd put some math puzzles with numbers on the walls or doors.

The best puzzle: the one with the dead guy :) I really loved that one.

Omfg you douchebag... You have to enable it after you install it and then start a new game OR load the part where you exit the vault. It's the most simple installation ever for me so go cry me a river.
