ChemLab aims to increase SMP experience by overhauling and adding mechanic to create different types of survival activities for players. This mod is not recommended for SSP until you want heavy challenge to be on your way: at least more than one player is advised.
This is all about processing materials and creating advanced autonomous stuff, effectively progressing through tiers. ChemLab Tiers are not the same as in the other ore doubling(tripling) mods ? by each tier you get access to more ways to process various resources flexibly changing outcome of your industrial empire.
For now this is PREVIEW version: there is only partial implementation of iron processing to show you how tiers and midtiers are going to be organized. Further parts of the mod will be released as big expansions for each major version along with minor bugfix versions. At the moment this mod IS NOT SUITABLE FOR STABLE GAMEPLAY due to some unfinished things in HOEnvironment which is base mod for ChemLab, providing some facilities to advanced features it posses. More information about them will be added later.
