If you haven't done this mission, give it a try.
It's a Lemurian mission given out by a contact named Floodgate where you board a Soviet Era Sub that's inhabited by radioactive communist zombies.
It sort of highlights the one complaint I had with Fatal Error-- the lack of music.
The mission itself wasn't spectacular in design-- though the map is nice enough-- but there's some Russian sounding music in the map which, IMO, totally made the mission exciting and fun to play.
Music CAN play a role in a map ... and that's one of the things that I think Champions does well or at least has in the past.
