Its probably going to be some MvM maps that have been fully finished but sitting around for years like pic related, because there is an absolute metric ton of MvM maps that have barely been played in the last 11 years because Valve basically forgot that MvM existed after the Two Cities update and most people who play MvM just play it for the crap that can drop from the tours.

I really don't think someone has enough time to throw together a map in 2 months compared to someone that has had 13 years to make an MvM map.
