Steamite

You have been assigned by a mining corporation to establish a thriving, but secret underground city. To provide a stable production of "steamite",  a new mineral with an incredibly high energy yield. The timeline starts at end of the first industrial revolution and continues past electrification (WIP).

Features that are implemented right now:

• Digging tiles and getting resources, if they contain any.
• Building new buildings on empty spaces.
• Production Buildings that convert some resources into another.
• Research Tree that unlocks new buildings and increases their stats.
• Connecting buildings with water/steam pipes to create a network.
• Map split into layers.

Features that are already implemented, but will be expanded a lot in the future.

• Trading with cities on the surface.
• Colony surface upgrades.
• Outposts providing periodic resources, that cannot be produced underground.
• Quests and orders.
• Human needs, efficiency modifiers
• Randomly generated map.

Features that will be added.

• Ground stability (cave-ins).
• Buildings and actions that modify the secret of the colony giving buffs/debuffs.
• Random events.
• Starting corporation and region. Both with map and difficulty modifiers.
• Sabotage, strikes,
• And hopefully more...
