Research

Description

In Forge of Empires, the player can research various technologies. These are required to unlock buildings and infrastructure, units and features like guilds. The most important thing about research is the progress through eras. As soon as one has unlocked any technology of a higher age, the player will progress to that age, unlocking buildings and upgrading the Town Hall.

Tech-Tree

The Tech-Tree is a visual representation of the progress through the ages and the technologies that one has researched and the ones that are yet to come. When hovering over a technology the green arrow(-s) pointing away from the current technology are the ones that are unlocked after this technology is researched. The arrow(-s) pointing to the current technology are the ones that are required for beginning the research. Otherwise, it's marked as a blocked technology.

A technology can be in one of these four stages:

• The technology has been fully unlocked.
• The technology has been researched but needs more resources or goods to be unlocked.
• The technology is currently being researched, so the Forge Point requirement hasn't been met.
• The technology is blocked, as one hasn't finished all the preceding researches.

Notes

1. ↑ The technology Multistory Houses (tech) requires 600 diamonds to unlock but is not necessary to progress.
2. ↑ ^{2.0 2.1} Promethium included.
