Brain of Cthulhu
I've been following this silently for a while; well before 1.3 was released. And I really, really hoped it was going to be in the game. I still do. I think the whole idea would fit in nicely as a Hallow alt, even for Crimson worlds if so desired. (I know the Cyber tends to be more popular, but I think the Covert fits in better.) To the point where in my main world, I partitioned off a part of the world, ready for Clentaminating in the hope a new biome was added. I ended up needing a new world anyway because of the underground desert. But I have partitioned off an area for it in my new world nonetheless.
I still hope the Covert or something like it will show up in a later update...
