找不到MOD文件夹，尴尬没办法改文件，我的Saved Games\Reassembly\data里没MOD文件夹

Dang I wish the unplayable Fern faction from ER was in this aswell

Actually, they have joined ExtraReassembly as unplayable factions. I think that all playable factions must be unique, but some elements of this mod's factions are repeated in ExtraReassembly - so they are currently unselectable in ExtraReassembly.
If you only want to subscribe to ExtraReassembly, and experience these 3 factions. You can use notepad++ to modify "factions. lua" :
change all "playable=0," to "playable=2,",and then, these factions will be playable.

I do not see the Urar in the Extra Rassembly Mod. Will they be added in?

Sorry. The durability of their blocks are about twice of the original "Terran", but because of smaller shapes, they are less effective against explosions. So, it can be thought of that they as the same strength/volume.

What i mean, are their blocks the same strenght/volume as vanilla blocks.

The size of basic block is about a half of "Terran", to be exact, 41.57%.

Cimpared to size/volume?

The strength of this faction is the same as "ExtraReassembly", just a little more powerful than "Terran" in original game.

Are they properly balanced compared to their strenght or are they OP?

No problem. I'm modifying some data of the blocks, and will upload a new version without these cvars tomorrow if I finished.

Please, do remove more than "some unnecessary content" from my cvars. While 12.5k is a lot, it is not nearly enough. More... is needed.

OK, I will try to remove some unnecessary content from cvars.

Can you separate the faction from the cvars?
