there was one already made on this server: net.connect 50.97.235.71:28715
you can go and check if it was built in the right way if you want. I had to destroy 2 metal doors and 2 or 3 metal walls for going there and at one point you are stuck and you can't continue but you can place a sleeping bed and spawn on the other side, or just throw grenades down and destroy everything. There is also another faster way to troll it and is destroying this wall here: http://i.imgur.com/olymeVP.jpg and throwing grenades down. I haven't tried with placing a sleeping bed there.

I made some picz:

I will try to build it again and check better the first foundation, maybe the position was wrong. Because I tried it some weeks ago and I was able to go inside there. The only solution for keeping it safe was building foundation on top.

lol yea I know it's not his technique, was a joke about how he wrote to refuse to show anyone the design,like nobody knows...xd

They cant get inside and take ur stuff or move in there a decoy base on the top. and if they go down they have to have material on them to get back up, and that only happens when you use metal.
In this base i build under the foundation too but i wouldnt recommend it.

And its not his technique same goes with building inside a rock ,it was the first exploit used and is against the rules on every server

have you checked that hole in the roof? the place where you wasn't able to place foundation. With foundation or not there (in this case you just have to jump down, place a barricade and box and jump on the foundation) people can move inside and get to your stuff. They just have to destroy the walls in the way. And if you have to place the boxes on the ground where they decay faster, you can use Uncle Friend's super secret technique and build under foundation lol. Faster, cheaper, easier, safer for your loot, but that is also an exploit.

Keep thinking that

Theres no unraideble Bases in Rust!

my bad about the other Unraidable too. That was my fault also XD

I know this sounds suss as all hell, but I refuse to show anyone the design for fear of it being patched. In all honesty, if the design was to be found out on a mass scale everyone would use it. It's too easy to make, unraidable and near impossible to find. Also, I don't want it to be patched. It appears Garry and team do not know about it yet, so we are keeping it close to our chests.

Remember when everyone was making those suicide bases as they were 'impossible' to raid? Imagine that, but EVERYONE in the server. No loot can be taken, no raiding can be done.

V--- Do it XD

I can make one with 40 planks. This is stupidly big and impratical.
