Snowy Planet

The Snowy Planet is arguably the hardest area in Destination Sol. The immobile turrets and ships inhabiting the Snowy Planet in Sol possess Advanced Shields, Advanced Armor, the two most "advanced" weapons in the game: the infinite-ammo Wave Gun and the ship-stunning EM Gun, along with the incredibly powerful Heavy Plasma Gun.

Due to the differing art style and unique weapons, it may be assumed that the inhabitants of the Snowy Planet are actually aliens, or something similar.
