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."

Im stuck where you get rescued by the helicopter. It,s probably a bug. When i enter the helicopter the door shuts in a way that i can see through it and when the load screens loaded i dont find myself from the helicopter but lieing on the ground in front of a gate and the worst part is that i'm lieing there, i can see my hud and cross but i cant move, instead my character tries to get up but wont and will keep triing until the and of times (or when i get tired and load an older save). Ive loaded it again and again but i still get the same glitch. Is there a way to solve this problem or do i have to do th whole cube all over again. Any suggestions welcome. Thank you.

I found a wierd glitch. At the part where you have turn to off the water pipe that's guarded by sentry guns, you can pick up grenades to use against them. I picked up a few, then went towards the first sentry guns, then got hit by them. A message came up saying that I couldn't equip broken items.

I went and picked up the other grenades, but they wouldn't appear in my hand. I now had infinite grenades. After turning off the water pipes, I went towards the room, in which I was blocked off by force fields. It said that I had to remove all items. So, I started throwing the grenades down the hole, but the glitch gave me infinite grenades, so I never ran out.

I'm now stuck in this room and i don't have a save to revert to. Is it possible that there is an item code that i can use to remove or unequip the grenades?

I found a save that was somewhat close to where I got stuck. This time, I did not encounter this glitch. But, in case anyone else runs into this glitch, the item code for the grenade is "01097e2c".

The mod is in the normal game, when you load a game up you should get a quest called "The Cube". Make it your active quest and you'll get a map marker showing you where The Cube is, go there and start this awesome quest.
