From the Steam store

In the depths of space, enemy forces are swarming toward your base. As commander, you must build and upgrade defensive installations within limited space and resources to withstand wave after wave of attackers. A dynamic tower-defense experience: enemies won't charge blindly — they detect, warn, and try to bypass your defenses, forcing you to constantly adapt your deployments.

Varied towers: towers with different functions can be combined freely to craft the strategy best suited to repel the enemy.

Strategic map design: each map features unique routes and nodes, and your choices directly affect the battlefield.

Escalating challenge: as waves progress, enemies grow stronger and smarter — you must upgrade your technology to survive.

Tense space atmosphere: with sci-fi visuals and immersive audio, the combat experience is intense and gripping.

Here, placing a single tower won't guarantee victory — you must think globally and respond flexibly. Only the wisest commanders will hold the last line of defense.
