Not sure what to do at the start? Here's a minute-by-minute action plan to get you through the most dangerous early phase.
很多新手开局不知道该做什么，这里给你一个分钟级的行动计划，照着做就能度过最危险的早期阶段。
-
0–3 minOpen every locker in the escape pod. Grab everything — especially the medkit and nutrition bar. These are your first lifelines.打开逃生舱里所有储物箱，拿走全部物品。特别注意：急救包、营养棒一定要拿，这是你最早的续命道具。
-
3–5 minPress Tab to open the PDA. Read all survival alerts — the PDA is your quest log. There's no quest tracker in this game.按 Tab 打开 PDA，读完所有生存警报。游戏里没有任务栏，PDA 就是你的任务书。
-
5–15 minDive in the 0–30m zone near the pod. Collect orange rocks (Titanium) and green-spotted rocks (Copper Ore), at least 5 of each. This depth is safe — no oxygen worries.在逃生舱附近 0–30米 范围下水，捡起橙色岩石（钛矿石）和绿斑岩石（铜矿），各捡5块以上。这个深度很安全，不用担心氧气。
-
15–20 minCraft a Standard O₂ Tank (Titanium ×1) in your fabricator. Equip it immediately — extends dive time right away. This is the #1 priority craft.用随身合成器合成：标准氧气罐（钛×1）。马上装备，潜水时间立刻延长。这是全游戏第一优先级合成。
-
20–25 minCraft a Knife (Titanium ×1 + Silicone ×1). Silicone comes from the orange mushroom-like plants near the pod — harvest by hand. The knife lets you collect plant samples and fend off small fish.合成刀具（钛×1 + 硅胶×1）。硅胶来自逃生舱附近的橙色蘑菇状植物，用手直接采摘。刀可以采集植物，也能击退小鱼。
-
25–35 minPlace a Beacon (Copper ×1 + Titanium ×1) outside your pod so you can always find home. Many beginners get lost on their very first dive.在逃生舱外放置一个信标（Beacon）（铜×1 + 钛×1），防止你以后找不到回家的路。这一步很重要，很多新手第一次探索就迷路了。
-
35–50 minCraft a Scanner (Titanium ×1 + Battery ×1). Battery needs Copper ×2 + Acid Mushroom ×2. Start scanning creatures and plants — each scan unlocks PDA entries and sometimes new blueprints.合成扫描仪（钛×1 + 电池×1），电池需要 铜×2 + 酸性蘑菇×2。开始扫描周围的生物和植物，扫描完成后 PDA 会解锁相关条目，有时会触发新图纸。
-
50–60 minFind a flat patch of seabed and place your first Base Foundation. Don't worry about the perfect spot — early bases can always be rebuilt. The goal is to start accumulating crafting stations.找一块相对平坦的海底，放置你的第一个基础舱（Base Foundation）。别担心选址不完美——早期基地随时可以拆了重建，关键是现在就开始积累合成台。
First 5 Things To Do刚开始要做的 5 件事
- Search every locker in the escape pod and grab the medkit, nutrition bar, and basic materials.检查逃生舱内的所有储物箱，拿走急救包、营养棒和基础材料。
- Press Tab to open the PDA and read all survival alerts — this is your mission log.按 Tab 打开 PDA，阅读系统自动发送的生存警报，了解当前优先任务。
- Dive in the shallows (0–30m) and collect Quartz, Titanium, and Copper — these craft everything.在舱外浅海（0–30 米）采集石英、钛矿石、铜矿，这是合成一切的基础。
- Craft an O₂ Tank (Titanium ×1) — your #1 priority. Extends dive time immediately.合成氧气罐（需要钛×1），这是最优先的合成目标，马上扩充潜水时间。
- Place a Beacon near your pod so you can always find your way back.在逃生舱周围放置一个信标，防止迷路找不到回家的路。

Co-op Tips & Warnings联机注意事项
The planet's ocean has 5 major biomes. Exploring shallow-to-deep is the safest progression. Don't skip tiers — entering a zone without the right gear means instant death.
星球海洋分为5个主要生物群落，按深度从浅到深探索是最安全的进度路线。不要跳过层级——没有对应深度的载具和装备，强行进入会直接死亡。
Zone Breakdown各区域详解
Your starting zone. Richest in resources, gentlest predators. This is your main mining area for the first few hours.游戏起始区域。资源最丰富，掠食者最温和。这里是你的主要采矿区，前几个小时几乎都在这里度过。
Massive floating kelp structures — visually stunning. Contains silver and rare plant samples. Needs the Seamoth to explore effectively. Sand Sharks follow you but won't attack unless provoked.巨型漂浮藻类结构，视觉震撼。含有银矿和特殊植物样本，需要海蛾才能有效探索。注意沙牙鱼会主动跟踪玩家，但不会主动攻击，离开即可。
Bioluminescent mushrooms hundreds of meters tall — one of the game's most beautiful areas. But Ghost Leviathan Juveniles patrol here — bring sound decoys. Needs Seamoth with Depth Module Mk.2.数百米高的巨型发光蘑菇覆盖整个区域，是游戏最美丽的场景之一。但幽灵幼虫在此出没，必须携带声诱饵绕行。需要海蛾二型（深度模块Mk.2）。
Extreme heat and pressure — requires Thermal Protection armor. Contains rare Diamonds and crystals. Dragon Eels and adult Ghost Leviathans guard it. Must use PRAWN Suit.高温高压区域，需要防热装甲才能进入。含有稀有钻石和稀有晶体。龙鳗和幽灵幼虫成体在此守卫。必须驾驶 PRAWN 外骨骼进入。
Endgame zone with the story's core content. Extreme environment — don't enter without full gear. Requires Sea Dragon submarine + full protective suit + massive supply reserves.游戏终局区域，含故事核心内容。极端环境，没有满配装备不要强行进入。需要海龙潜艇 + 完整防护套装 + 大量物资储备。
Predator Threat Levels & How to Respond掠食者威胁等级与应对
| Creature生物 | Zone区域 | Threat威胁 | Response应对方法 |
|---|---|---|---|
| 🐠 Sand Shark沙牙鱼 | Shallow–Mid浅-中层 | ⭐⭐ | Swim away — doesn't attack first, just ignore游离开，不主动攻击，无视即可 |
| 🦈 Bone Shark骨鲨 | Mid-depth中层 | ⭐⭐⭐ | Throw a sound decoy, then detour声诱饵丢出后绕行 |
| 👻 Ghost Leviathan (Juv.)幽灵幼虫（幼） | Mushroom Forest蘑菇林 | ⭐⭐⭐ | Decoy + accelerate Seamoth to escape声诱饵 + 海蛾加速撤离 |
| 👻 Ghost Leviathan (Adult)幽灵幼虫（成） | Deep zone深层 | ⭐⭐⭐⭐⭐ | Wide detour — run on sight, do not approach不要接近，绕远路，看到就跑 |
| 🐉 Dragon Eel龙鳗 | Lava zone熔岩带 | ⭐⭐⭐⭐⭐ | PRAWN Suit to absorb hits, or wide detourPRAWN 外骨骼抵御，或绕行 |
Two golden rules:
① Surface when oxygen hits 30% — don't keep mining those last few rocks;
② Craft the High Cap O₂ Tank (Titanium ×3 + Glass ×1) — it gives 3× more dive time. Upgrade ASAP.
Also: use the surface → breathe → dive rhythm. Don't try to maximize every single dive.
溺死是新手最常见的死法。记住两条铁则：
① 氧气低于30%立刻往上浮，不要再贪心继续采集；
② 合成高容量氧气罐（钛×3 + 玻璃×1）比标准罐多3倍时间，一定要尽早升级。
另外，水面换气是免费的，多用"出水→换气→再下去"的节奏，不要一次潜太久。
Subnautica 2's design philosophy is "explore for yourself" — no markers is intentional. The right approach:
① Open the PDA (Tab) — all story clues are inside, updated whenever you scan a wreck or creature;
② Follow the wreckage — ship debris on the surface and in shallow water triggers new content when approached;
③ Just swim and enjoy — the best finds are accidental. Embrace the exploration.
Subnautica 2 的设计理念就是"自己探索"，没有任务箭头是故意的。正确的探索顺序：
① 读 PDA（Tab键）——所有故事线索都在里面，每次扫描残骸和生物都会更新；
② 跟着残骸走——水面和浅海会有大量坠落的飞船残骸，走近就会触发新内容；
③ 不要想太多，随便游就行——好东西都是"意外"发现的，享受探索本身。
Completely normal — the developers deliberately designed thalassophobia. Practical tips:
① Use your lights — darkness is the biggest fear source, always keep the Seamoth headlights on;
② Carry decoys — Sound Decoys (Magnetite ×1 + Plant ×1) distract most mid-tier creatures;
③ Scan everything — the PDA shows behavior patterns after scanning; knowing what triggers it reduces fear drastically;
④ Most creatures don't aggress first — leave them alone and they'll leave you alone.
这是正常反应！开发者专门设计了"深海恐惧感"。几个降低恐惧的实用技巧：
① 开灯——黑暗本身就是恐惧来源，随时开海蛾车灯；
② 带诱饵——声诱饵（磁铁矿×1 + 植物×1）能把大部分中型生物引开；
③ 了解生物——扫描仪扫过的生物会在 PDA 里显示习性，知道它吃什么才会攻击，恐惧感会大幅降低；
④ 大部分生物不会主动攻击——你先不碰它，它一般不咬你。
Both work — each has trade-offs:
Solo: More immersive, you control the pace, no one takes your resources, and the fear factor is legendary (in a good way).
Multiplayer: Resources accumulate 4× faster, teammates divide the danger, large creatures less frightening. Better for players who don't enjoy isolation.
Recommendation: Solo first playthrough for the story experience, then co-op for a fresh run with role specialization.
两种都可以，但各有优缺点：
单机： 体验更完整，自己掌控节奏，不用担心别人拿走你的资源，恐惧感更强烈（褒义）。
联机： 资源积累快4倍，有队友分工更安全，大型生物遇到时不那么怕，适合不喜欢孤独感的玩家。
建议：第一次玩先单机体验剧情，二周目再联机体验全新分工乐趣。
Flooding means Hull Integrity hit zero. Fix steps:
① Build Reinforcement Panels (Titanium ×3 + Glass ×1 = +7 integrity each) to restore structure;
② Use a Repair Tool to right-click and fix each crack;
③ If heavily flooded, swim out first, add panels, then repair the cracks;
④ Every 100m of depth costs ~1 integrity — always build reinforcement panels before expanding a deep base.
基地进水说明结构完整性降到0了。解决步骤：
① 先建造加固隔板（钛×3 + 玻璃×1）补强结构，每个提供 +7 完整性；
② 用修复工具在漏水点右键修复裂缝；
③ 如果大面积进水，先游出基地，加足够的加固隔板后再修复漏洞；
④ 基地深度每增加100米就消耗约1点完整性，注意提前准备加固隔板再建深层基地。
Subnautica 2 has a day/night cycle. At night the underwater world goes pitch black, and fear doubles. How to cope:
① Stay at base at night — organize inventory, craft gear, wait for dawn;
② If you must go out, turn on all lights and bring Flares (throwable for area lighting);
③ Some creatures are actually quieter at night — experienced players exploit this, but beginners shouldn't;
④ Certain deep creatures have different night behaviors — PDA entries reveal these patterns.
Subnautica 2 有昼夜循环，夜晚水下一片漆黑，恐惧感翻倍。应对方法：
① 夜晚留在基地——整理物资、合成装备，等天亮再出发；
② 如果要出门，开全部灯光，随身携带荧光棒（丢出去照明）；
③ 夜晚有一些生物反而更安静，有经验的玩家会利用夜晚探索——但新手不建议。
④ 某些深层区域的生物在夜晚有不同的行为模式，扫描仪可以查到。
Three ways to unlock blueprints:
① Scanner on wreck fragments — find crashed ship debris underwater, scan 4 fragments of the same type to unlock a blueprint;
② Repair Tool on wreck circuit boards — approach a damaged circuit panel on a wreck, repair it, sometimes gives a new blueprint;
③ Read PDA data logs — some blueprints auto-unlock through story events.
Summary: find wrecks, scan everything, read every PDA entry — blueprints pile up naturally.
图纸解锁有三种方式：
① 扫描仪扫描残骸碎片——在水下找到飞船残骸的碎片，靠近后用扫描仪扫，扫满4片解锁一张图纸；
② 修复工具修复残骸电路板——靠近有损坏电路板的残骸，用修复工具修复，有时会给新图纸；
③ 读 PDA 里的数据记录——有些图纸通过故事事件自动解锁。
总结：多去找残骸，多扫描，多读 PDA，图纸自然越来越多。
