Bullet Heaven Idle

Build the most beautiful barrage in the universe — then sit back and watch it work. Bullet Heaven Idle is a relaxing idle shooter set in a strange two-dimensional world of glowing life. You are a single luminous cell, drifting through the dark, surrounded by an ever-growing swarm of your own offspring. Together you unleash a constant, mesmerizing storm of light against everything that comes for you. There is no ship to steer here. Your cell moves and fires entirely on its own — your role is to shape what it becomes. ■ AUTO-FIRE, ALWAYS PROGRESSING Your cell and its Options fire on their own — and move on their own. You never control the ship directly. Instead, you choose its patterns, place its Options, and decide what to upgrade. Progress continues whether you are playing actively or not — perfect for filling a few quiet minutes, or for leaving running while you do something else. Come back later and your time away is waiting for you as rewards to collect. ■ 24 BULLET PATTERNS TO COLLECT Unlock bullet patterns through the gacha and equip them individually to your cell and each of your eight Options. Homing, Laser, Shotgun, Sniper, Wave, Burst and more — each in Normal, Quick and Heavy variants. Mix and match to design a barrage that is entirely your own. ■ ARRANGE YOUR SWARM Drag your Options anywhere on the grid. Their position changes how your barrage spreads across the screen. Two players with the same patterns can build two completely different storms of light. ■ ENDLESS STAGES AND TOWERING BOSSES Push through hundreds of stages, each denser than the last. Clear the gauge to summon a Stage Boss that fights back with your own unlocked patterns. Face the great Bosses that mark every fifth stage. ■ DESCEND INTO THE DEPTHS Enter the Deep Dungeon, where there is no clear condition — only how long you can survive. Rewards multiply the deeper you go. Escape with what you have, or push your luck a little further. ■ MADE TO BE CALM Soft bioluminescent light against deep space. Gentle sound. No timers demanding your attention, no punishment for stepping away. Bullet Heaven Idle is designed to be a quiet, satisfying place to return to. ■ NO ACCOUNT, NO SERVERS No sign-up, no login, no online connection required to play. All your progress is stored on your own device, and you can delete it whenever you like. The only time the App goes online is when you choose to watch an optional ad for a bonus. Grow your swarm. Shape your barrage. Watch the dark fill with light.
