Abandoned Facility mode(Just an idea)
#1Could be an unlockable, a secondary mode, not very large, about 15 minutes of gameplay (something like scp-087-b). You have to enter the facility (after the Breach) to clean it, search for scaped SCPs or something. Abandoned facilities are always creepy, so we should take advantage of this.
DON'T SHOOT! LET THEM BURN!
