The Four Upgrades at a Glance
Before diving into priority, let us quickly review what each upgrade does and why it matters:
| Upgrade | Primary Effect | Max Level | Direct Income Impact |
|---|---|---|---|
| Max Depth | Mining depth range | 4 levels | Very High (better ores) |
| Backpack Size | Ore carrying capacity | 5 levels | High (longer mining runs) |
| Ore Limit | Processing pipeline capacity | 7 levels | Moderate-High (more throughput) |
| Plot Size | Base physical space | Multiple | Indirect (enables more machines) |
The income impact column is key. Upgrades with direct income impact (Max Depth, Backpack Size) should generally be prioritized over indirect upgrades (Plot Size) and throughput upgrades (Ore Limit) in the early game. However, the optimal order changes as you progress.
The Universal Priority Framework
After extensive analysis and community feedback, here is the universal priority framework that works for the vast majority of players:
Phase 1: Income Foundation -- Max Depth and Backpack Size Phase 2: Processing Capacity -- Ore Limit Phase 3: Infrastructure -- Plot Size Phase 4: Optimization -- All upgrades to maximum
This framework is based on a simple principle: invest in upgrades that directly increase your income first, then invest in upgrades that enable you to process that income efficiently, and finally invest in infrastructure that supports your full setup.
Detailed Priority Order by Game Stage
Stage 1: Tutorial (BP1-BP2)
At the very start, you are learning the game mechanics and building your first basic setup. Your priorities here are straightforward:
| Priority | Upgrade | Level | Reason |
|---|---|---|---|
| 1 | Forge (BP1) | N/A | Required to sell ores |
| 2 | Mineral Washer (BP1) | N/A | First value multiplier |
| 3 | Max Depth Level 2 | 25-75m | Access better ores |
| 4 | Backpack Size Level 2 | 250 ores | Longer mining runs |
The Max Depth upgrade at Level 2 should be your very first upgrade purchase. The improvement from surface ores to 25-75m ores is immediately noticeable and will accelerate every subsequent upgrade. The Backpack Size Level 2 upgrade comes right after to support longer mining runs at the new depth.
Stage 2: Early Game (BP3-BP5)
In the early game, you are expanding your refiner chain and building your income foundation:
| Priority | Upgrade | Level | Reason |
|---|---|---|---|
| 1 | Ore Limit Level 2 | 10 ores | Support 3-4 refiner chain |
| 2 | Backpack Size Level 3 | 400 ores | Support mid-depth mining |
| 3 | Max Depth Level 3 | 75-150m | Access uncommon ores |
| 4 | Ore Limit Level 3 | 20 ores | Support growing chain |
The Ore Limit upgrade becomes important here because your chain is growing beyond what a 5-ore pipeline can support. Upgrading to 10 ores, then 20 ores, ensures your refiners stay busy processing.
Stage 3: Mid Game (BP6-BP8)
The mid game is where upgrade decisions become more nuanced. You have multiple competing priorities, and the optimal order depends on your specific setup:
| Priority | Upgrade | Level | Reason |
|---|---|---|---|
| 1 | Max Depth Level 4 | 150-300m+ | Access rare ores |
| 2 | Ore Limit Level 4 | 30 ores | Support Industrial Forge chain |
| 3 | Backpack Size Level 4 | 600 ores | Support deep mining |
| 4 | Plot Size | First upgrade | Room for mid-game machines |
Max Depth Level 4 is the highest priority in the mid game because the rare ores at 150m+ are dramatically more valuable than anything you have been mining. This single upgrade can double or triple your income per mining run.
Stage 4: Late Game (BP9-BP11)
In the late game, you are pushing toward S-Tier machines and the Nuclear Forge:
| Priority | Upgrade | Level | Reason |
|---|---|---|---|
| 1 | Ore Limit Level 5-6 | 40-55 ores | Support S-Tier refiner chain |
| 2 | Backpack Size Level 5 | 1,000 ores | Maximum mining efficiency |
| 3 | Plot Size | Second upgrade | Room for S-Tier machines |
| 4 | Ore Limit Level 7 | 70 ores | Maximum throughput |
The Ore Limit upgrade becomes the top priority in the late game because your S-Tier refiners need a full pipeline to operate efficiently. Without adequate ore processing capacity, even the most powerful machines in the game will sit idle.
Stage 5: Endgame (BP12-BP13)
At the endgame, you are maximizing everything:
| Priority | Upgrade | Level | Reason |
|---|---|---|---|
| 1 | All remaining Ore Limit levels | 70 ores | Maximum pipeline capacity |
| 2 | All remaining Backpack levels | 1,000 ores | Maximum carry capacity |
| 3 | All remaining Plot Size levels | Maximum | Full base optimization |
| 4 | Max Depth Level 4 (if not done) | 150-300m+ | Access all rare ores |
By the endgame, you should have most upgrades at or near maximum. The focus shifts from choosing between upgrades to completing all remaining levels for the best possible setup.
Cost-Benefit Analysis
Understanding the cost-benefit ratio of each upgrade helps you make informed decisions when you are low on resources. Here is a simplified analysis:
| Upgrade | Cost Level | Income Increase | Payback Period |
|---|---|---|---|
| Max Depth Level 2 | Low | 2-3x | Very Fast |
| Backpack Size Level 2 | Low | 10-20% | Fast |
| Max Depth Level 3 | Moderate | 2-3x additional | Fast |
| Ore Limit Level 2-3 | Low-Moderate | 50-100% | Moderate |
| Max Depth Level 4 | High | 2-3x additional | Moderate |
| Backpack Size Level 5 | High | 10-15% additional | Slow |
| Ore Limit Level 7 | Very High | 10-15% additional | Slow |
| Plot Size | Variable | Indirect | Very Slow |
The upgrades with the fastest payback periods are Max Depth and early Backpack Size levels. These should always be your first investments. Later upgrades have diminishing returns and longer payback periods, so they can be deferred until your income is high enough to afford them comfortably.
Common Upgrade Mistakes
Mistake 1: Upgrading Plot Size Too Early
The most common mistake new players make is upgrading Plot Size before they need the space. A larger plot does not increase your income -- it only gives you room to build more machines. If your current plot has empty space, do not upgrade. Wait until you literally cannot fit the machines you need.
Mistake 2: Ignoring the Ore Limit
Many players focus on Max Depth and Backpack Size while neglecting the Ore Limit entirely. This leads to a situation where they mine lots of valuable ores but their processing chain cannot handle the volume. The result is a backlog of ores waiting to enter the pipeline, which means idle machines and lost income.
Mistake 3: Maxing One Upgrade Before Starting Others
Some players max out one upgrade category before touching any others. For example, they might upgrade Backpack Size to Level 5 before buying any Max Depth upgrades. This is inefficient because the upgrades have synergistic effects. A larger backpack is more valuable when you are mining deeper, rarer ores. A higher ore limit is more valuable when you have more refiners in your chain. Balance your upgrades for maximum combined benefit.
Mistake 4: Forgetting About Equipment Upgrades
While this guide focuses on the four main upgrade categories, do not forget about equipment upgrades like pickaxes, drills, and lights. Better equipment lets you mine faster and deeper, which directly increases your income. Equipment upgrades should be incorporated into your overall upgrade strategy, not treated as a separate concern.
The Optimal Upgrade Sequence
Here is the single best upgrade sequence for most players, from start to finish:
| Step | Upgrade | Estimated Total Cost So Far |
|---|---|---|
| 1 | Max Depth Level 2 | Low |
| 2 | Backpack Size Level 2 | Low |
| 3 | Ore Limit Level 2 | Low |
| 4 | Max Depth Level 3 | Moderate |
| 5 | Backpack Size Level 3 | Moderate |
| 6 | Ore Limit Level 3 | Moderate |
| 7 | Max Depth Level 4 | Moderate-High |
| 8 | Ore Limit Level 4 | Moderate-High |
| 9 | Backpack Size Level 4 | High |
| 10 | Plot Size (first upgrade) | High |
| 11 | Ore Limit Level 5 | High |
| 12 | Backpack Size Level 5 | Very High |
| 13 | Ore Limit Level 6 | Very High |
| 14 | Plot Size (second upgrade) | Very High |
| 15 | Ore Limit Level 7 | Very High |
This sequence balances income increases with processing capacity, ensuring you always have the infrastructure to support your mining output. Adjust as needed based on your specific situation, but this order works well for the vast majority of players.
Frequently Asked Questions
What should I upgrade first in Tectonic Industries?
Max Depth Level 2 should be your first upgrade. It immediately gives you access to better ores that are worth 2-3x more than surface ores. After that, upgrade Backpack Size Level 2 to support longer mining runs at the new depth.
Should I upgrade Plot Size or Ore Limit first?
Ore Limit should come before Plot Size in almost every situation. The Ore Limit directly increases your processing throughput and income, while Plot Size only enables you to build more machines. Upgrade Plot Size only when your current plot is too small for the machines you need.
How do I know which upgrade to buy next?
Ask yourself: what is currently limiting my income? If you are mining low-value ores, upgrade Max Depth. If you are making too many trips back to base, upgrade Backpack Size. If your machines are idle, upgrade Ore Limit. If you cannot fit your machines, upgrade Plot Size. The answer depends on your specific bottleneck.
Can I undo an upgrade?
No, upgrades in Tectonic Industries are permanent and cannot be refunded or reversed. Choose carefully and follow the priority order in this guide to ensure you make optimal decisions.
Is there an optimal order for all upgrades combined?
Yes, the sequence provided in this guide is the optimal order for most players. It balances immediate income increases with long-term capacity building, ensuring you always have the infrastructure to support your growing operation.
Should I save up for expensive upgrades or buy cheap ones first?
In general, buy the cheap upgrades first. They provide the best value for your money and quickly pay for themselves. The expensive upgrades at later levels have diminishing returns, so they can wait until your income is high enough to afford them comfortably.
