About This Game

Humanity’s greatest crisis is an ordinary day at work.

Aster: Harvest Log is a story-driven sci-fi action-adventure with defense-style combat and anime-inspired characters. Play as Rias, a laid-back alien officer assigned to collect resources on Earth. Towering over cities and armies, she discovers that the tiny creatures beneath her feet are more organized than she first imagined.

Take direct control of Rias as you move across the battlefield, stomp through advancing troops, and pick up soldiers and military vehicles for a closer look. Choose where to step, which threats to handle, and when to use your equipment. At this scale, even an everyday tool can overwhelm humanity’s defenses.

Between missions, return to the Aster to report your findings and spend time with its eccentric crew. Explore the ship, examine what you have brought back, and follow conversations that turn an alien expedition into a surprisingly familiar workplace.

Experience the encounter from both sides through illustrated story scenes. While Rias and her colleagues trade jokes and work through their assignments, human soldiers and commanders struggle to understand—and survive—the visitors above them. Lighthearted banter meets military desperation in a story shaped by vast differences in scale, knowledge, and empathy.

For a separate combat challenge, enter Endless Mode. Face escalating assaults, choose upgrades, take on recurring tank bosses, and push for a longer survival record.
