Yes, you heard right, Thunder Mountain in MVM, the Capture The Flag version, in this case. Several new platforms have been added to allow the robots and tanks to traverse through the map by foot, and the Mannpower logic has been removed. Due to how this map works, I found it fitting to add Caliginous Caper (AKA Wave 666) to this map's missions besides the already classic "testmission", instead of mvm_mannworks' missions. Have fun trying to beat it!
Due to unnaturally and absurdly long normal compile times in this map, it is rendered with a fast HDR compile. I will try to fix this in the future.
