The Last War Tech Center is the main hub for permanent research progression. Its technology branches improve construction, resource production, event performance, troops, and later account progression.
However, there is no single research order that remains optimal forever. Your priority changes as new branches and seasonal systems become available. This guide gives you the big-picture research path and directs you to the dedicated guide for each major branch.
What Does the Tech Center Do?
The Tech Center lets you research permanent technologies instead of simply increasing building levels. Some branches improve general account efficiency, while others are connected to specific events, military milestones, or later seasonal systems.
As a result, upgrading the Tech Center is only part of the progression. A high-level Tech Center is most useful when its research queues remain active and the technologies you select support your current goal.
If you are upgrading your Headquarters and need the actual building prerequisites rather than research advice, use the Last War Headquarters Upgrade Guide.
Last War Tech Center Research Guide Hub
Instead of duplicating every technology tree here, use the following guides for the detailed mechanics, costs, and priorities.
| Research / Progression | Main Purpose | Detailed Guide |
|---|---|---|
| Development & Economy | Construction, research speed, resource production, gathering, and account growth | Development & Economy Research Guide |
| Alliance Duel | Research connected to Alliance Duel scoring and rewards | Alliance Duel Guide |
| Intercity Truck | Research supporting truck dispatch, rewards, and plundering | Intercity Truck Guide |
| Special Forces | Advanced military research and the path toward Unit X / T10 | Special Forces Research Guide |
| Age of Oil | Oil production, additional late-game research capacity, and post-HQ-30 progression | Age of Oil Guide |
| T11 / Armament | Late-game troop-tier progression outside the normal Tech Center trees | T11 Troops Guide |
Start with Development and Economy
For a developing account, Development and Economy provide the foundation for everything that follows. They improve areas such as construction efficiency, research efficiency, resource production, gathering, training support, and base capacity.
These bonuses are especially valuable when acquired early because they continue helping throughout later Headquarters and research progression.
Do not copy a complete node order from a general Tech Center guide. The dedicated Development & Economy Research Guide covers which nodes to prioritize and which can wait.
Use Alliance Duel Research for VS Progression
Alliance Duel research should be viewed together with the Alliance Duel event rather than as an isolated Tech Center tree. Its value depends on how actively you participate in VS and how efficiently you convert saved resources into event progress.
For daily themes, scoring, reward strategy, preparation, and the related research, use the Last War Alliance Duel Guide.
Intercity Truck Has Its Own Research Path
Intercity Truck research supports a specific daily system rather than general base development. Because research decisions are closely connected to dispatches, cargo rewards, defense, and plundering, separating the research from the truck mechanics would make both guides less useful.
The Last War Intercity Truck Guide therefore owns the complete truck system and its research priorities.
Special Forces Leads Toward T10
Special Forces becomes one of the major military research investments as your account develops. Most importantly, its progression eventually leads to Unit X and the T10 troop milestone.
Because the branch has its own prerequisites and Valor Badge costs, this hub does not reproduce the node list. Use the Special Forces Research Guide for the required path, costs, and spending priorities.
T11 Is Not Another Tech Center Tree
A common progression mistake is assuming T11 simply continues from Special Forces. It does not.
Later T11 progression moves into the Armament Institute and uses its own research system. Therefore, this Tech Center hub only points to the Last War T11 Troops Guide rather than duplicating Armament requirements or costs here.
Age of Oil Changes Late-Game Research
After Season 2, Age of Oil introduces another major progression stage involving Oil, new research, additional research capacity, and the route beyond the normal HQ 30 ceiling.
The third Tech Center is tied to this Age of Oil research progression rather than simply appearing because you reached HQ 30.
For Oil sources, Oil Well priorities, the Age of Oil research sequence, and Base Expansion, use the dedicated Last War Age of Oil Guide.
How to Choose Your Next Research
When several branches are available, choose research according to your current bottleneck rather than spreading resources evenly across everything.
- Need faster account growth? Focus on Development and Economy.
- Preparing for Alliance Duel? Review the VS-related research and event strategy together.
- Working toward T10? Continue the required Special Forces path.
- Trying to improve Intercity Trucks? Use the dedicated truck research priorities.
- Entering post-Season-2 progression? Prepare for Age of Oil.
- Already preparing for T11? Move your planning to Armament Research instead of ordinary Tech Center research.
Common Tech Center Mistakes
Researching Every Branch Equally
Different branches solve different problems. Prioritize your current progression objective instead of trying to keep every tree at the same percentage.
Confusing Tech Center Level with Research Progress
Upgrading the building improves your research infrastructure, but it does not automatically complete the technologies that matter to your account.
Assuming T11 Continues Special Forces
Special Forces leads toward T10. T11 later uses the separate Armament Institute progression system.
Assuming HQ 30 Automatically Gives the Third Tech Center
The additional late-game research capacity is connected to Age of Oil progression. Follow that research path rather than expecting the building to unlock from HQ level alone.
FAQ
What should I research first in Last War?
For most developing accounts, Development and Economy are strong starting points because their bonuses support long-term construction, research, and resource progression.
Which Tech Center research unlocks T10?
Unit X in the Special Forces research branch is the key T10 milestone. Use the dedicated Special Forces guide for its prerequisite path.
Does Special Forces unlock T11?
No. T11 progression later moves to the separate Armament Institute and Armament Research system.
Is Intercity Truck research worth doing?
It can improve the value of the Intercity Truck system, but its priority depends on your account stage and other research goals. The dedicated truck guide covers the individual technologies.
How do I unlock the third Tech Center?
The third Tech Center is tied to Age of Oil research after Season 2. Reaching HQ 30 alone is not the complete unlock process.
What happens to research after HQ 30?
Age of Oil becomes the major late-game progression branch, introducing Oil-based development and the route toward buildings above level 30.
Conclusion
The Last War Tech Center should be treated as a research hub rather than one giant tree with a universal priority order. Build your early foundation through Development and Economy, then invest in specialized branches as your account, events, and seasonal progression require them.
Use the dedicated guides above whenever you need exact node priorities, costs, or unlock requirements. For more progression and strategy articles, browse the Heaven Guardian Last War Survival guides.
