The mining and crafting systems are getting an overhaul: Resources will be collected, transported, and refined into useful materials in new ways. Augmenting that will be a reformed death and cloning system. Players will drop all non-bound items in their inventory on death, and the process of creating a new clone to get back into action with will be lengthier (although it can, of course, be sped up for a cost.) Players will now be able to create and manage their own factions, rather than sticking with the eight factions that were previously in the game.
There's more! There's so, so much more (including "stuff with aliens"). Keep an eye out for a Kickstarter campaign to fund new improvements and systems for the game.
