Hoi mn6 and rmc22,
Sorry to tell you that your map have been rejected.
The theme seems to be interesting and original if we look at the name. The build however is not good, it's really plain and unattractive, and the build don't really looks like a Vault in my opinion. The parkour could be better, it's pretty varied, which is cool, but it's way too hard for an expert, and even a bit too hard for an insane in my opinion (We can also skip the cross "neup" Inside the Vault where there is gold blocks).
Thanks for submitting your map, would be really good to see more maps from you !
