Reasonable Realism Harder Underground & Hazards

Mining is no longer a safe activity. Harder Underground introduces physics and atmospheric dangers that require careful planning.

Collapse Physics

When mining stone or ore, there is a chance to trigger a Collapse. This causes ceiling blocks to fall, potentially crushing the player. To prevent this, players must use Support Beams.

• Vertical Beams: Placed to support the ceiling directly above
• Horizontal Beams: Connect two vertical beams to create a "Support Zone" (typically 9x5x9) where blocks are safe from falling

Underground Gases

Three types of dangerous gases can accumulate in unventilated mine shafts:

• Methane (Firedamp): Highly explosive. It can be ignited by torches or fire, causing massive explosions
• Carbon Monoxide (Whitedamp): Odorless and toxic. It causes a slow drain on health and vision impairment
• Hydrogen Sulfide (Stinkdamp): Highly toxic and corrosive, often found near certain ore types

Block Hardness

To simulate the difficulty of manual labor, the hardness of "soft" blocks like dirt, sand, and gravel has been increased. Wooden tools are now required for efficient digging, and punching these blocks is significantly slower.
