Old Elysium
The latest creation from D'Arcy Industries, here to give you the building blocks of an industry of nightmares.
Old Elysium aims to add new worlds (and a 'moon') of exploration, branching tech trees, MMORPG style classes, skills and abilities, automation and heavy industry, and many options in terms of decorations and character customization. The content added can be broken into 5 branches, Clock's Work, Elemental Industrial, Questionable Ethics, Parallel Terrestrial, and Professional Professions.
However, currently only basic decorative blocks and items ranging from metal and bio materials to terrain blocks are available in creative (check the Images tab for previews). This is a work in progress and it takes time to make/implement all that this mod aims to add, so please bear with us. Also of note; This mod is also designed to be played with the Create mod.
