The following flow covers the core steps from launching the game to completing a game session.
Step 1: Create/Load Game Project

Step 2: Basic Movement and Exploration
- Movement: Left-click a target point on the ground, and the character will automatically pathfind and move there. Movement consumes Action Points (AP).
- Sprinting: Hold the
Shiftkey while left-clicking a distant location, and the character will sprint (consumes more AP, but covers a greater distance). - Exploration & Interaction: Hover the mouse over an object or person. Once a prompt appears:
- Left-click: Perform the default interaction (e.g., pick up an item, talk to an NPC).
- Right-click: Open a detailed interaction menu (e.g., “Search Container,” “Examine,” “Use”).
Step 3: Combat and Conflict Resolution
Upon encountering enemies, the game automatically switches to turn-based combat mode.
- Combat Turn Order: A turn order bar appears on the right side of the screen, showing the action sequence for both allies and enemies.
- Performing Actions: When it’s your character’s turn, you can perform the following actions (all consume AP):
- Move: Left-click a reachable position on the battlefield.
- Attack: Click a weapon skill icon (e.g., “Melee” or “Ranged”), then left-click to select a target. Alternatively, right-click a target directly and select “Attack” from the menu.
- Use Item/Skill: Click the hotbar number key, or right-click the item bar to use.
- Defend/End Turn: Click the shield icon to the right of the action point bar or press the
Spacekey.
- End Combat: After defeating all enemies, you will automatically exit combat mode and can loot battle spoils.
Step 4: Character Progression and Quest Advancement

Cto open the character panel, where you can see assignable skill points and new feats that may be unlocked. - Quest Tracking: Press
Jto open the journal. Active quests will display objectives and descriptions. The yellow diamond on the minimap points toward the objective direction of your currently tracked quest. - Dialogue Checks: In dialogue, if a skill icon appears next to an option (e.g., [Eloquence 55%]), it means selecting that option requires passing the corresponding skill check. The success rate is based on your current skill value.

~/Library/Application Support/ATOM/folder under your user directory. You can back up this folder to export or transfer your saves.
III. Advanced Tips for Common Features
3.1 Efficient Item Management
- Quick Transfer: In the container or merchant interface, hold the
Ctrlkey and click on an item to quickly transfer a single item between the container and your own inventory. - Batch Operations: In your inventory, right-click on a stack of items (such as ammunition) and select “Split” to divide it into two parts.
- Quick Equip: In your inventory, drag a weapon or armor icon onto your character portrait to equip it quickly.
3.2 Combat Optimization
- Preset Attack Modes: After selecting an attack in combat, you can right-click the target and choose “Attack Body Part” from the menu to target specific body parts for special effects (e.g., attacking the legs to reduce enemy mobility).
- Use Environment: After moving behind an obstacle, you gain a Cover bonus, increasing your armor class (AR).
- Action Point Retention: Unused AP from each turn (up to 3 points) can be carried over to the next turn. Making good use of this mechanic allows you to make multiple attacks or move long distances at critical moments.
3.3 Exploration and Dialogue
- Fast Travel: On the world map screen, click on a discovered settlement or landmark and select “Fast Travel” to arrive instantly (requires being out of combat and the location must be explored).
- Dialogue History: During conversations, move your mouse to the top of the screen to display previous dialogue records, making it easy to review key information.

Ctrlkey to enter stealth mode. While sneaking, move behind an enemy (displayed as “Backstab” status) before attacking to trigger a first strike and gain a huge advantage.
IV. Common Issues and Solutions
Issue 1: Game crashes on startup or won’t open
Possible Causes: Incompatible macOS version, graphics driver issues, or corrupted game files.
Solutions:
- Confirm that your Mac meets the game’s minimum requirements (usually macOS 10.12 or higher).
- Try checking “Run in Compatibility Mode” or “Use OpenGL Rendering” in the launcher or game properties (if the option exists).
- Verify the integrity of game files (through the game platform you purchased from, such as Steam or GOG Galaxy).
Issue 2: In-game text displays abnormally or shows garbled characters
Possible cause: Missing font files or conflicting language settings.
Solution:
- In the game’s main menu or settings, confirm that the language is correctly set to “Simplified Chinese.”
- Try temporarily switching the Mac system language to English, launch the game, and then switch it back to Chinese.
Issue 3: Save files lost or corrupted
Prevention and solution:
- Regular manual backups: Periodically copy the
~/Library/Application Support/ATOM/folder to another location. - Use multiple save slots: Avoid always overwriting the same save; rotate between 2-3 save slots.
- If a save file is corrupted, try restoring it from a backup, or use an earlier autosave from within the game.
Issue 4: Combat difficulty too high or stuck on a level
Strategy adjustments:
- Lower the difficulty: You can adjust the difficulty level at any time in the game settings.
- Use stealth tactics: Use stealth to avoid unnecessary combat, or use area-of-effect weapons such as landmines and grenades against groups of enemies.
- Level up: Leave the current area, complete other easier quests to gain experience and level up, then return.
- Equipment Check: Make sure you have the best weapons and armor available at your current level, and keep your weapons in repair status.
