JusTD

JusTD is a tower defense game with resource gathering and base management. You reveal hidden sections of the map, build defenses and start waves of enemy robots that try to reach your main tower. Some attack other buildings and turrets if they can, while boss-level robots appear in certain waves with much higher stats; if one reaches your base, the mission ends immediately.

Build and defend

You can build and sell buildings, but building spaces are limited, so you must choose what to place and where. Turrets gain levels and become stronger as they attack enemies, so keeping them intact matters. You mine and refine minerals for resources, which you can spend on building or repairing structures and turrets, or producing ammunition.

Game modes

Skirmish lets you choose a map and its day cycle. In Campaign, you advance through missions of increasing difficulty. Some Campaign missions include environmental hazards such as meteor strikes and earthquakes; you can also select these hazards for Skirmish maps.

To progress in the Campaign, you must reach the minimum wave limit on each map and enter the Endless wave state. After that, a new wave starts automatically when the last enemy is killed, making the game significantly harder. The game records the highest wave reached on each map in both Skirmish and Campaign.

Late-game support

You can use an Orbital strike after killing enough enemies.
