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

epic mod. i searched every nook and cranny but i could only find 14 holomarks. whoever hid them was good at hiding stuff.

and btw, at the end of the game, the case takes my suit (which is too bad cause that suit is awesome), gives me back my weapons and stuff, but doesnt let me unequip the energy melter.

help please?

mh .. doesn't really work.
I've installed the .exe so far.
After starting the F3, the game is crashing.
Got the v1.7 (F3) latest Patch.

I think I've found a bug.. all the Power Fists in the game are called Power Fausts now.. And I'm almost sure it's from this mod, because it's the only mod I have installed.
OR it changed with the DLCs, but I don't think that's what happened.
