AsteroidTD

AsteroidTD is a tower defense game set in open space, where you build across an endless field of asteroids rather than defending a fixed base or a single path. You expand your colony while protecting a small spaceship that flies independently around the battlefield.

Build across space

You have four building types: one to capture asteroids, one to protect them, one to mine gold and one to conduct research. There are 18 types of asteroids, each of which affects the buildings placed on it, and a research tree with 161 sub-items. You can strengthen your defenses, improve your economy, expand your influence or build a compact fortress.

Defend your colony

Enemies attack from all sides and target your towers before the builder spaceship nearby. Equip asteroids with enough turrets to protect your buildings. The spaceship can also build new structures and provide support.

Records and relaxation

You can compete with friends to set records or play with calm ambient background music.
