@JanKaszanka: I'll assume you mean "smeltery" as the stone building. Anyways, that was a good choice, the smeltery is always warm and is made of lava-resistant stone.
I accept the ice underground base design.
@JanKaszanka: Slow down! You only got enough fur for some boots. How the hell are you supposed to cross the ocean that fast? You did however get the chests and the boat.
I hide in the underground of that stone building
@Nathan: How about a underground base made of permafrost and ice? To save warmth, you cover the entrance with snow. The radioactive uranium keeps you warm.
@JanKaszanka, the comet will not, the meteor shower will. Prepare or die!
