You may have seen the pictures already and there's a download link going around, to save you from a potential virus we're hosting it ourselves so you can play it safely.
(You can verify that I am legit with my steam profile)
Here is the file hosted on my own server, you'll need to extract it from the bz2: http://www.subtleallusion.com/files/stuff/cp_snowplow_b1.bsp.bz2
Alternatively just download it from the TF2M servers. The info is: 70.42.74.31:27015 for US and 91.121.155.109:27015 for EU
This is still a work in progress, many things are subject to change and pretty much nothing is 100% final. We're looking for feedback on everything except visuals and clipping, so team balance, class balance, flow, etc. If you're playing on our TF2M servers you can use our feedback plugins by typing with ingame chat:
!fb leaves locational feedback with your location and your crosshair's location
!gf leaves general feedback for when you don't care about a location
If you'd rather get in touch directly, you can find me on Steam, and Frozen on steam or you can leave your feedback here in this (Reddit) thread and we'll read it.
We're also recording demos and heatmap data so just by being there and playing you're contributing.
We've taken anything out that might be a little spoilery for the video, but for the sakes of those who'd rather wait until it's finished, please don't go posting images/videos without spoiler warnings. Thank you and have fun!
EDIT: post+1hr. We had some miscomunication about files, our own servers were running the right ones but a broken one got put on my site, my site now has the correct one but if you grabbed it from my site in the first hour you're gunna have some errors. We'll roll out to _b2 to fix this soon.
