Our good friend, Rogue13 has been working diligently on a Halloween themed map and has granted us access to this awesome map. It's a KOTH map with a twist. It's a Halloween boss roulette map. Which means you'll get Merasmus, Monoculus, Headless Horsemann, etc. The map also has a few other things. Check it out here: http://steamcommunity.com/sharedfiles/filedetails/?id=782407483
We tried to play it last night and unfortunately it crashed the server pretty early on. I have removed it from the nominate list. I wouldnt be surprised to see Rogue releasing an update soon.
I really hope this maps gets updated real soon. The idea of having all of the Halloween bosses in one map is pretty awesome. Compound that with spells and you have a challenging map on your hands.
