Underground Testing Center

To say this is bassed off portal would be an understatement.

The first 3 levels of this... are almost exact copies of portal.

I've been working on my server with this, after an underground mining facility was turned into a iron clad room. Running only Vanilla, i started building a "relaxation Vault" just because, and its turned into this.

10 rooms, 7 secrets, ALL VANILLA (no mods)

Currently though only 3 out of the 10 levels have been made, the others are drawn out on paper and being built.
