Competition's have been lacking lately, in that there have been none.
So my idea for this month was a Vault Competition. Basically, create your own vault. It can be an existing one you have already made, I log of events giving some insight into the vault, or blueprints of a completely new one.
Or come up with your own idea for the Vault Competition and submit it.
I don't usually do the competitions, so forgive the briefness.
Remember - "The Vaults weren't built to save anyone"
