No badlands biome, just like in the first movie?
Probs not for base game, Desert is pretty close to it in terms of challenges (
As much as I'd like to see all angles of hoodoo). The DLC might end up in that direction, you never know.
Thinking about the Dev Diary, it's pretty clear there's 4 sets of rocks, each intended for an environment (
The Desert rocks first row, the Taiga rocks third row, possibly the Tropical rocks second row).
I don't know if rocks might get reused between a few biomes, or if certain rocks are left out of the Desert map/s, but for the moment 4 environments overall (
including the tropical islands) should be the assumption, leaving room for only one biome we haven't seen from base game.
