Protect your planet in an epic cosmic battle!

Planet Defense: Space TD is a tower defense game set in space. You defend a home planet against waves of alien invaders by placing defenses, upgrading them and arranging them so they work well together. The listing describes it as a roguelike, so each attempt plays out differently.
It fits players who like planning a defense in advance and then adjusting it as the waves change. The listing presents it as easy to pick up, with mastery depending on planning and quick decisions during a battle.
The build we hold is Planet Defense: Space TD 0.1.80 (APKS split bundle) for Android 10 and up.

The main defenses are called sentinels. You unlock and upgrade them over time, and each one has its own abilities. The listing says combining different sentinels is part of the strategy, since some pairings are meant to handle stronger enemies than others.
Building and upgrading are the core actions. You spend a run deciding which sentinels to place, where, and when to improve them, with the aim of holding off foes that become harder with each wave.
Each playthrough is built with randomized upgrades and challenges, according to the listing. Because of this, two runs will not present the same choices, and you need to adjust your plan to what you are offered.
The roguelike structure means a run is the unit of play. Progress and options depend on how each attempt goes rather than on a single fixed path through the game.
Levels are procedurally generated, so the layout of each battle is created by the game rather than taken from a fixed map. Multiple difficulty modes are also offered, letting players choose how hard the invasion will be.
Together, generated levels and difficulty choices are the listing's main answer to replay. The developer says these combine so that no two battles are the same.
The listing describes the game's visuals as detailed and its sound design as atmospheric, aimed at an epic space setting. Controls are presented as intuitive, so placing and managing defenses does not require a long learning curve.
These are the developer's own descriptions. The listing gives no further detail on how the visuals or audio are presented during play.
