Additional hazardous biomes

[Wurtstool]

I love it when DST updates contains entirely new biomes and the last full land biome we got was the lunar grotto/archives? (moon quay barely counts as a full biome) Here's to hope that Klei adds more in future updates or refresh old ones they feel up to par with the newer ones they added.

I feel like that there should be more biomes that you need to be prepared to enter, for example the ruins as its possibly the most fun place to explore because of the danger and reward. Here are few examples that come up to mind:

Lava tunnels:

caves biome where it would be extremely hot to enter so heat repellent gear is very recommended. Would contain lava falls, magma pools, rare ore such as obsidian while battling hostile mobs that can easily set you on fire. 

Tundra biome:

surface biome where vision is obscured by a snowstorm and warm gear is required to fight off the ongoing permafrost. Can have snowbanks hiding valuable loot, ice related mobs, and maybe year round Mactusks so tusks aren't time gated.

Temple biome:

cave biome similar to the ruins but is structured like the geometric archives with square rooms and long hallways. However unlike the ruins, the place will be littered with deadly traps, secrets, and puzzles you need to solve to progress. Of course any temple would not be tempting to brave without good loot.
