Thank you to everyone who submitted their missions for Foundry Challenge #5, and for all the discussion in this thread! From today until Wednesday, January 9th at 10AM PST, voting will be open. Please see this thread for voting information.
I can't find the mission Cold Enemies by Q400, i'm done a custom search using the name "Cold Enemies" and I've searched by Author which only turns up one misison called "Hunter Killer: Part 2". I'll be going on to the next mission while waiting for a response.
Edit: Nevermind I wasn't a reviewer before, now I am and I can find it fine.
It used to be when you clicked the Review Content button at the bottom there would be Start Reviewing or something like that. Not sure exactly where it is post season 7, but I imagine somewhere similar.
To find my mission if no one has played it yet, most likely it needs to be reviewed first, before it shows up as a normal foundry mission. By becoming a reviewer you should be able to find it.
Edit - Like this screenshot. 3rd tab on the left and at the bottom. Become Reviewer.
