Planets Extended has moved! Due to the upcoming update, Mars will be conflicted so I created a new system for my planets (they may move again later to an existing system). It is the lower-right on the star map. The system has some appearance issues that will be fixed in an upcoming patch. (I wanted to get this update out before the vanilla update)
This mod will extend (most if not all) the unused planets in Aground and add a couple new ones.
Mercury (now Iron Planet) - has a landable area, some enemies (the magnewyrms will probably be changed), and it is not yet complete. (I plan to possibly add more enemies, perhaps an NPC, and a surprise) It has a variety of ores, including: sulfur, quartz, titanium, and exotic matter. It is a no oxygen planet. The core is liquid iron, but I am still working on it so it is unmineable at this point.
Mars (now Red Planet) - has a landable area, an enemy (rogue rovers), has no oxygen, and is also not yet complete. (I plan to possibly add more enemies and the remains of a colony [the aliens would have bombed that out also, so it could be more like earth]). As with Mercury, it has a variety of ores, including two new ones, aluminum and magnesium, that are used to make steel-bars (they make a steel-like alloy, so it's close enough). The upper ores on Mars are similar to those on the actual planet, and it includes bands of ice underneath the surface as the real planet also has.
One of the planets now has another npc. It allows one quest (a "find" one) by calling his planet on the com station. He allows construction of a new structure, but the resources are vastly more than the structure is currently worth. It will have an interior area with structures in the next major update.
The system for these two planets has no text or graphics, but is fully-functional. Mercury is the inner planet.
More Mars and Mercury content,
The next major update will be a while because my computer isn't running well. I will try to release a patch soon to fix the system appearance.
Please let me know of any un-stated bugs and suggestions.
Known issues: The planets and system don't have names in the star map, Iron Planet is not on its orbit line, and the planets don't have animations. The code is also rather messy because of my work on the update. It will be cleaned up when the next major update comes out.
The Com station has two windows that appear. Orbit escape bug for Mercury and Mars. (I still have no idea why that happened).
david_maletz for the nice graphics and dwarf planet Mercury (and Mars to some extent) is modeled after.
me for bad graphics and code
