Tundra planets are similar to the Terran starter planets, except frozen and colder. They can consist of flat plain-like frozen land, or large mountains. They generally contain higher tier materials.
On the surface, Hydrazine is plentiful, along with the occasional Titanium and Lithium deposit. Large deposits of Coal can be found under the surface in caves. Laterite and Malachite is scarce and can be found sparsely in the deepest caves. Resin is scarce in the mountains of the Tundra planet.
The average time it takes for a day/night cycle to pass is 20 minutes.
