It's beginning to look a lot like the opposite of Christmas, what with the warm weather and sunshine and all. Terraria doesn't really care what the weather's like, though, and it's going to add a little winter cheer whenever it darn well pleases. Artist Jimmarn recently revealed screenshots showing a snow biome along with underground ice caverns that will be part of the next update. When that update hits is anyone's guess (June?), but it's going to be a massive one.
