Safe House progression: research, workbenches, and permanent upgrades
The Safe House has several progression gates, not one upgrade tree. Research entries can require a discovery item, specific materials, already-known blueprints, a research-table tool, and a particular workbench. Treat newly found tools and uncommon materials as possible unlock keys until you have checked the table.
What research actually checks
| Requirement | Why it matters | Player habit |
|---|---|---|
| Discovery item | Some research only appears once you have found its named starting item. | Inspect the research table after bringing back unfamiliar materials or equipment. |
| Research-table tool | Some projects need a specific tool installed at the table, such as 多功能工具钳. | Do not sell a named tool just because it is not field gear. |
| Materials and blueprints | Research can consume supplies and can also require blueprints you already know. | Keep a small reserve of specialist salvage instead of converting every piece into immediate supplies. |
| Workbench blueprint | Each project names a workbench, and finishing the project needs that workbench's blueprint to be unlocked. | Check the workbench column in the Research Table guide before you gather materials. |
Choose the station for the bottleneck
| Station | Role | When it becomes a useful priority |
|---|---|---|
| 基础工作台 | Processes more materials than Handcraft and supports basic tools and components. | When the research table points you to general materials, tools, or components. |
| 简易子弹制作台 | Makes ammunition. See Crafting ammo and weapons for every recipe. | When ammunition, rather than weapons, is limiting your next trip. |
| 烹饪台 | Turns ingredients into cooked meals and refills Satiety, Blood Sugar and Hydration in the Safe House (2 a second each). | When food ingredients are accumulating and satiety recovery would help your regular routine. |
| 基础医疗站 | Provides early medical support and slowly restores Safe House Health. | When recovery between trips is the problem you are trying to solve. |
| 中级烹饪台 | Upgrade of the 烹饪台 with a 4×4 input grid instead of 3×3. It refills Satiety, Blood Sugar and Hydration in the Safe House the same way. | When you want a larger grid for cooking. Its blueprint comes from the mission 厨房改造. |
| 简易锻造炉 | Makes ingots, steel and charcoal. | When factory ammunition needs iron ingots or steel. The mission Furnace awards its blueprint. |
Handcraft remains its own option for recipes that do not need machinery. A station is a requirement for the recipes and research that name it; it is not a blanket improvement to every craft.
A useful research loop
- Bring back new materials, tools, and blueprints instead of selling them immediately.
- At the Research Table, open a project and read every missing requirement.
- Unlock the named workbench's blueprint only if that requirement is what is stopping the project.
- Complete the research, then check the newly unlocked blueprint or furniture before spending the remaining materials.
These are concrete chains from exploration through research to new crafts, not merely a menu to clear:
| Project | Key requirements | Station | Unlock |
|---|---|---|---|
| High-Frequency Radio | 多功能工具钳; broken facility, electronic component, common circuit board, and broken wires. | 基础工作台 | High-Frequency Radio blueprint. |
| Improved Bandage | Medical alcohol, a bandage, and the two basic bandage blueprints. | 基础医疗站 | Improved Bandage blueprint. |
| 《维修手册》 | 多功能工具钳, 《维修手册》, abandoned firearm, broken armour, and broken helmet. | 基础工作台 | Patched-helmet and patched-armour blueprints, plus Cook Squad Field Armour. |
| 《野外生存手册2》 | 多功能工具钳, 《野外生存手册2》, deer hide, and durable stitches. | 基础工作台 | Deer-skin pouch, gloves, leggings, face armour, and vest blueprints. |
Furniture and corruption systems
Buildable furniture can open entirely separate systems. The 回溯器 handles Corrupted items, while the 退相干反应釜 is described as a station for special processing of dimensional corruption. Read the blueprint or mission that awards each one before reserving its materials; they are not interchangeable crafting benches.
