Terrain Terraforming & Player-Created Tunnels

Hello,

I would like to suggest a terrain terraforming mechanic, specifically allowing players to dig and create their own underground tunnels instead of relying only on predefined underground areas.

Given the miniature scale and survival focus of Grounded 2, this feature could greatly enhance immersion, player creativity, and emergent gameplay.

Core Idea

Allow players to modify the ground to create tunnels, burrows, shortcuts, and hidden bases. The goal is not full sandbox destruction, but controlled, rule-based digging that fits the survival design of the game.

Gameplay Mechanics

Digging Tools

• Basic shovel for loose soil

• Reinforced tools for clay and compact ground

• Advanced or endgame tools for deeper or harder terrain

Different soil types would affect digging speed, stamina cost, and tool durability.

Soil Types & Constraints

• Loose soil: easy to dig, but unstable

• Clay: slower to dig, suitable for underground bases

• Roots and rocks: obstacles that block or limit digging

• Infested soil: triggers hostile creatures

Poorly supported tunnels could collapse unless reinforced with structures.

Underground Threats

Digging would attract underground creatures such as:

• Burrowing insects

• Large worms or centipedes

• Aggressive ant patrols

The deeper or louder the digging, the higher the risk of encounters.

Strategic Uses

• Creating shortcuts between biomes

• Escaping predators

• Building hidden underground bases

• Setting traps or ambush routes

Some enemies could invade or destroy poorly defended tunnels.

Balance Considerations

To keep the system fair and performant:

• High stamina and durability cost

• Restricted zones (near story locations, bosses, or map limits)

• Depth limitations without advanced gear

• Chunk-based terrain saving to preserve performance

Why This Fits Grounded 2

• Reinforces vertical exploration (surface and underground)

• Deepens survival and risk-reward decisions

• Encourages unique player-made worlds

Terraforming would give players a stronger sense of ownership over the environment while staying true to the game’s survival identity.

Thank you for considering this idea !
