HOW TO READ A RESEARCH TREE IN A STRATEGY GAME

An unlock is the beginning of a plan

A research tree is a map of possibilities. It tells you which capabilities can follow which earlier discoveries. The strategic part is deciding which possibility your current position can actually use.

A common trap is to evaluate a technology only by its final reward. The new facility sounds useful, so you start the research. Later you discover that the base still needs electricity, staff, road access or another facility before the reward can do anything. The technology was real progress, but it was not the whole project.

This guide offers a method you can apply while reading a strategy game’s own rules. The worked example uses Mars47’s version 1.0.7 opening campaign through Chapter 5. It is not a claim that every game uses the same costs, queues or prerequisites.

Read three kinds of prerequisite

Knowledge prerequisites connect one research topic to an earlier topic. They tell you the route through the tree.

Physical prerequisites connect research to the world you have built. A laboratory level, an operating tank or an available workforce can matter just as much as an earlier discovery.

Campaign prerequisites connect availability to your current stage or objectives. A useful technology can appear in the interface before it is the right next commitment.

Separating those questions makes a locked entry easier to understand. “What do I need to know?”, “What must already exist?” and “When is this available?” are different checks. Repeatedly selecting a locked topic will not resolve a missing facility.

Work backward from a useful result

Begin with something specific you want to accomplish, then trace the dependencies backward. Keep the result small enough to verify: supply the test stand, complete an objective or support the next building. “Improve everything” is too vague to guide spending.

1. Choose the outcome.What will become possible when the work is complete?
2. Trace the research.Which earlier topics and facility levels are required?
3. Check the base.Can access, power, staff and construction support the result?
4. Reserve the full commitment.Allow for the implementation after the research itself.
5. Verify the outcome.Check that the capability is operational, not merely unlocked.

This approach makes the tree serve a plan. You can still change direction when a new opportunity appears, but you will know what that change delays.

A Mars47 example: propellant research needs working infrastructure

In Mars47, Rocket Propellant I requires Propulsion Engine I and two operating tanks. That makes it a useful example of a research dependency crossing into construction. An earlier technology alone is not the whole requirement.

Work backward from the desired research entry: inspect the earlier topic, then inspect whether the required tanks are operational. If they are not, investigate their actual status and dependencies rather than assuming that a placed building has already fulfilled the requirement. The research handbook gives the exact topic requirements, and the building handbook covers the facilities.

The next distinction is between research and evidence from testing. Researching propulsion is not the same event as completing an engine qualification objective. The Chapter 3 walkthrough explains the test sequence in its campaign context.

Budget for the capability after the breakthrough

For a simple planning exercise, imagine a technology that costs 100 credits and unlocks a facility costing 400. If you reserve only the research cost, you have not funded the usable result. If that facility also needs another power source, the real commitment is larger still. These are illustrative numbers, not Mars47 prices.

In a game, inspect the actual construction costs, supporting services and any recurring commitments it models. Consider what other objective will wait while those resources are tied up. A cheaper research option may be more valuable now if the base can put it to work immediately.

Mars47’s Chapter 5 grid connection is a concrete reason to look ahead. The western farm, installed generation target and utility connection are separate parts of the objective. An earlier energy breakthrough does not remove the need to fund and complete the physical work.

Choose a useful order without pretending there is one universal build

Start with the capability that removes a current blocker or enables a clearly planned next step. Then consider optional improvements against the same question: will they change what the base can achieve soon, or simply add an attractive entry to the completed list?

There is room for exploration. Sometimes learning how a new system behaves is worth a detour. The point is to make that choice deliberately, with a clear view of the resources it uses and the objective it postpones.

In Mars47, follow the current mission directive alongside the research screen. A topic being researchable and a chapter requiring it are different facts. For exact timings, prerequisites and unlocks, use the full research reference; for the intended sequence, start with the chapter guides.

When research appears stuck, inspect the chain

1. Read the current entry and mission objective.
2. Check the earlier research topics.
3. Check the required facility and its level.
4. Check whether physical prerequisites are complete and operational.
5. Inspect the relevant access, power, staffing and queue status.
6. Return to the objective and confirm which result it counts.

This gives you a reproducible way to investigate a blocker. It also captures why research can be satisfying in a building game: a breakthrough changes the meaning of what you have already constructed, and a stronger base makes the next breakthrough possible.
