Terra Nil (Chinese title: 伊始之地) is a unique reverse city-building game where the player’s goal is not expansion and conquest, but rather transforming barren wasteland into a thriving ecosystem. This guide will provide a detailed introduction to the core interface, complete operation flow, and advanced tips for its Mac version.
I. Core Interface and Workspace Detailed Explanation
The game interface is centered around a minimalist design and is divided into the following functional areas:
- Main Map Workspace: Occupies the center of the screen and displays an isometric view of the current terrain. Ecological regions such as wasteland, water bodies, and forests are distinguished by distinct color blocks.
- Building and Tool Panel: Usually located at the bottom or side of the screen, displaying in card form the facilities that can be built at the current stage (such as wind turbines, irrigation pumps, detoxifiers, etc.).
- Resources and Progress Bar: Located at the top of the screen, displaying the currently available “recycling points” resource, as well as the three core indicators of ecological restoration: green coverage, biodiversity, and purity.
- Stage Objective Panel: Located on the right side of the screen, clearly listing the objectives that must be completed in the current restoration stage (for example: establishing a certain area of forest or wetland, or attracting specific animals to return).
Tab key to activate it, highlighting different ecosystem regions (such as grasslands, wetlands, and forests) with semi-transparent colored blocks for easy planning.II. Complete Operation Walkthrough: From Start to Export
Phase One: Create and Start a New Game
After launching the game, use the mouse or trackpad to click the “Start Game” button in the main menu. Select “New Game” to enter the map selection screen.
The game offers multiple regions (such as Tropical Valley, Volcanic Archipelago, etc.). Use the arrow keys or mouse clicks to select your preferred map. Some maps require completing prerequisite objectives to unlock. Once selected, you can choose “Casual” or “Challenge” mode; the latter imposes stricter resource management requirements.
Phase Two: Basic Terrain Modification (First Stage)
After the game begins, you have a small amount of “recycling points.” Click the Wind Turbine icon in the bottom panel, then click to place it on high ground on the map to maximize power generation efficiency. This is the starting point for all energy.
Location: Building panel.
Method: Build a Toxin Scrubber to purify brown barren land. Then, build an Irrigator next to the purified green grassland, and drag its arrow to adjust the irrigation direction, creating contiguous grassland areas.
Shortcut: After selecting a building, press the R key to rotate the building’s orientation (e.g., to adjust the Irrigator’s direction).
Use a Water Pump to draw water from a water source (blue area), then connect and build a River Dredger to extend the river. On the silt along the river’s path, build a Fynbos Weir to create a wetland ecosystem.
Phase Three: Ecological Diversification (Second Stage)
Place an Arboretum on silt, and the silt within its area of effect will gradually grow into a forest. Make sure the area has been irrigated and fully purified.
Location: After unlocking the second stage, animal habitat buildings will appear in the building panel.
Specific Method: Each animal requires a specific combination of ecological conditions. For example, deer need adjacent forest and silt. Place the corresponding animal habitat (such as a deer habitat) in an area that meets the conditions, then wait for the animals to return and increase biodiversity.
Phase Four: Recycling and Departure (Final Stage)
Once all three metrics—greenery, biodiversity, and purity—reach 100%, the game enters the final stage. At this point, the building panel changes to “Recycle Buildings” (such as Drone Center, Airship, etc.).
Strategically place Drone Hubs on the map; all buildings within their range will be automatically recycled, returning resources. Use the returned resources to build the final Airship. Once all man-made structures have been recycled and only the pristine ecosystem remains, click the Airship to complete the level and watch the beautiful evacuation animation.
III. Advanced Tips for Common Features
- Precise Coverage Planning: Make good use of the
Tabkey to toggle the ecological coverage overlay. Before placing a building, check its area of effect (usually shown as a semi-transparent circle) to ensure maximum coverage of the target terrain. - Efficient Resource Chain Management: Follow the chain of “Energy → Purification → Irrigation → Ecosystem Creation.” Prioritize building multiple wind turbines on high ground and at windy spots to ensure sufficient power.
- Synergy Between Terrain and Buildings: Rivers can irrigate the soil on both sides. When planning river channels, make them flow through areas that need irrigation for as long as possible—killing two birds with one stone.
- Stage Objective Priority: Always use the Stage Objectives on the right panel as your primary guide. Completing all objectives automatically advances you to the next stage and unlocks new buildings.
- Undo Operation: If you make a mistake, you can immediately press
Command (⌘) + Zto undo the last building placement.
IV. Common Issues and Solutions
Issue 1: Insufficient power, unable to construct new buildings.
Solution: Check whether the existing wind turbines are located in areas with sufficient wind (indicated by white airflow animations on the map). Demolish inefficient turbines and rebuild them in locations with stronger wind. Alternatively, temporarily recycle non-essential buildings to free up power.
Issue 2: Animals do not return to their habitat.
Solution: Click on the animal habitat building to view its detailed requirements. A common cause is that the surrounding environment does not fully meet the conditions (for example, it requires “adjacent forest and wetland,” but one of these ecological areas is insufficient). Use the Tab overlay to check and expand the corresponding ecological zones.
Issue 3: Unable to reach 100% purity.
Solution: Purity requires recycling all buildings. Make sure that in the final stage, you use the drone center to cover every corner, including isolated buildings in remote areas. Zoom in (mouse scroll wheel) and carefully inspect the entire map.
Issue 4: Game stuttering.
Solution: Lower the graphics quality in the game settings, especially the “Shadows” and “Water Quality” options. Close unnecessary background applications to free up system resources.
