A hand-drawn survival tower defense on a hostile alien world. No fixed lanes — every building you place reshapes the swarm’s path in real time. Command engineer Mulan, trigger spore-driven chain reactions, and keep the last Purification Core alive.

Crash-landed on a dying alien world. The planet itself wants you gone.
You are Mulan, a ship engineer. The crash scattered your crew, and all that is left beside you is one running Purification Core. As long as it glows, the corruption stays out — and you stay sane. Deep in the wasteland, the swarm has already caught the scent of an outsider.
This is not memorize-the-track tower defense. Enemies path dynamically across open terrain: every turret and every wall you place rewrites their route to you. Shape the battlefield like an RTS — funnel, split, corner, then focus fire.
Alien creatures are not stat sticks — they react to each other:
Sproutlings burst into spore clouds when hit and leave corrosive remains when they die;
Zerglings that charge into a spore cloud go into allergic frenzy — faster attacks, paper-thin defense;
Control kill order and kill position, and let the swarm blow itself up.
Mulan is no spectator behind the walls:
Weakpoint Scan — mark enemies for your whole defense to focus down;
Shockwave Knockback — blast backline threats away from your towers (the recoil sends her flying too);
Requiem Echo — a forbidden technique reverse-engineered from the enemy. High risk, last-resort insurance.
She also critiques ballistic deviation, gives her frost tower a nickname, and nags you to build when you idle.
Gale Turret: rapid-fire physical damage, the backbone of your line;
Frost Tower: zero damage, pure control — freeze the tide to create focus-fire windows;
Ore is scarce. Where you build, and what you build first, is always a trade-off.
The Core is your lifeline: upgrade it to expand the purified zone; lose it and it is over. Each wave hits harder, and every gap in your line will be punished.
Ink lines and watercolor textures: wastelands, glowing fissures, colossal skeletons and your wrecked ship. Cute art, cruel situation.
The demo contains Chapter 1, Level 1 (about 10–20 minutes): 1 playable hero, 2 tower types, 2 enemy species and the full spore-chain tutorial.
In development for the full game: deck-building cards, the three-essence economy, more towers/enemies, elites & bosses, more chapters. Wishlist to watch it grow.
Steam lists 孢子风暴:荒星防线 as coming soon without a confirmed date yet.
