About Research Lab

Priority: High

The Research Lab (1st Lab) is where you unlock and upgrade technologies that permanently boost your city's combat strength, resource output, and construction speed. Research benefits stack and persist — it is one of the highest long-term ROI investments in the game.

Upgrade Tips

1Prioritise combat research (troop attack, defence, HP) for PvP; prioritise economy research for faster progression.
2Research is permanent — every point spent here is a compounding advantage.
3Keep your Lab upgrading whenever resources allow — downtime here is wasted long-term potential.
