About

Sky Guardian

Read full description

Sky Guardian is an offline bullet hell space shooter. Drag to move, dodge enemy fire and keep shooting as you push through the ASHFALL campaign. Learn each boss pattern, earn upgrades and try a different ship for your next run. It is free to play, supported by ads, with no in-app purchases. Fly the ASHFALL campaign across 100 chapters as an Aether storm swallows one system after another. Worlds bend the rules with hazards such as icing, poison fog, wind and gusts, meteor strikes, black-hole pull, time distortion, and more — so survival is about dodging as much as shooting. A world map, story dialogue, and a named boss battle at the end of every single chapter carry you from the first wave to the final storm. Upgrade your ships between runs and take down 100 bosses across the campaign. FEATURES - 100-chapter story campaign on a chapter-select map, across escalating acts of danger - 100 named bosses — one per chapter, with title cards, weak points and battle music, drawing on 15 attack patterns; crack the cores, don't chew a bullet sponge - 16 flyable ships, each a true sidegrade with its own feel and signature weapon — armored patrol, glass-cannon interceptor, rapid-fire gunship, juggernaut - 25 distinct worlds with unique visual identities, music moods and changing battlefield conditions - Deep hangar: 8 permanent upgrade tracks, 12 modular ship parts, and a SPECIAL MODULE slot with own-and-equip modules and run boosts - STORM CORES and the SINGULARITY climax — late bosses pull the arena apart before they die - 8 modes: Campaign, Sky Runner, Endless, Survival, Boss Rush, Time Attack, Chaos, and ASCENSION — each with its own records - ASCENSION roguelite mode — draft power-up cards, bank a single life, and push a permadeath run as far as your build takes you - End-of-chapter card drafts and weapon combinations for run-specific builds - 41 tiered achievements, a companion drone, escort missions, daily objectives with streak bonuses, a weekly challenge, and a pilot level system - 28 engine-trail colours, from the standard wake to gold and mastery unlocks - COMMUNITY LEVELS — paste a compatible shared code to play a custom stage. No account required. - Dynamic, biome-reactive music that shifts mood per world, with adaptive low-HP tension BUILT RIGHT - Full touch controls (drag to move, on-screen pause and bomb) plus keyboard support - The campaign plays offline — no internet connection needed to fly (ads need a connection to load) - Free to play, supported by ads: full-screen ads appear between runs, an ad may appear when you open the game, and optional rewarded ads let you revive or double your coins. No in-app purchases, no account system - Your save is stored locally; no account or sign-in is required. Advertising privacy choices are available in the game settings when applicable. The game does not request contacts or location access. If you grew up on classic arcade shmups and vertical scrolling shooters, this space shooter is built for you: readable bullets, honest hitboxes, boss battles that reward pattern-reading, and a difficulty curve that respects your time. No wifi, no paywall — just you, your spaceship, and the storm. Break the storm, crack the cores, and reclaim the sky.
