Pattern Survivors: Bullet Hell (Roguelike) is a dynamic action game where you take control of your space tower and design your own attack patterns to fend off hordes of enemies!

🛠️ How to Play – Jump into the action in 3 seconds — no tutorials, no waiting, just play!

1️⃣→ Add a probe/emitter

2️⃣→ Configure the probe/emitter in a simple editor using sliders

3️⃣→ Press the "Start Battle" button and watch the effects!

Unlike classic bullet hell shooters, here YOU decide what your attack looks like. Place emitters/probes, configure patterns using sliders, and create unique bullet sequences to dominate the battlefield! You can modify your attack patterns in real time, adjusting your strategy for each new wave of enemies.

For each wave you defeat, you earn experience points — level up and choose from powerful upgrades that enhance your tower or emitters!

⚔️ Sample Upgrade System:

Tower Reinforcement – increases your tower’s maximum health.
Emitter Spikes – damages enemies that get too close to your emitters.
Electric Aura – shocks enemies near the tower.
Reflective Shield – some damage is reflected back at enemies.
Railgun – a powerful energy beam that pierces everything in its path.
Emitter Fortification – turns your emitters into obstacles that block enemy movement.
Auto-Repair – your tower automatically regenerates health.

🚀 Game Modes:

Normal – classic survival mode.
Story – discover the mystery of the space station and learn the origins of the attack patterns.
Survival – endless waves of enemies to test your skills.
Sandbox – play with patterns and test any setup without limits.

✨ Game Features:

Controller support (gamepad), mouse and keyboard, etc.
Steam Achievements
Steam Leaderboards (online rankings)
A simple, unique bullet hell pattern editor using sliders!
Save/load patterns (share them with friends, e.g. JSON)
Real-time pattern editing
Tower and emitter upgrade system
Roguelike with high replayability
Retro graphics inspired by 90s SHMUP (Shoot 'em up) games
Auto-battler but you have special skills that affect the game — mines, time slowdown, sniper shot, and more. Use them with keyboard shortcuts and aim at enemies/levels.
Time control (speed up or slow down, play the way you like)
Bullets can have different patterns and colors, e.g. pink.
"Save and Quit" system hibernates the game so you can play another game on Steam, then return at any time. Or, for example, if you need to eat dinner, you can leave and come back later, then select "Continue" from the menu.

Create your own fighting style and prove you can survive the chaos of bullet hell patterns!

UPDATE 1.5.7 almost 1,000 units sold

Hello!

[img src=\"https://cdn.cloudflare.steamstatic.com/steamcommunity/public/images/clans/45651685/40158d46fdf31057c91601cf285d8f29ee5fe8d9.gif\"][/img]

Solo dev here. Thanks to your support, the game has now reached almost 1,000 players which is huge for a project this small. As a thank-you, heres a small update that touches almost every version of the game and cleans up a few important systems under the hood.

[hr][/hr]

Full update across all versions

Updated the full version and demo on all platforms:\nWindows 32-bit, Windows 64-bit, Linux 64-bit, Mac 64-bit, and the browser version.\nNo matter where you play, youre now on the latest build.
[/*]
Updated localization files to prepare for further translations and text fixes (including some artifact and achievement descriptions).
[/*]

[img src=\"https://cdn.cloudflare.steamstatic.com/steamcommunity/public/images/clans/45651685/0a527daac998d759eb407f0fa6e929247b01808c.png\"][/img]

[hr][/hr]

Quality of Life faster access to rewards

Added a SKIP ANIMATION button to the DATA CORE animation.\nIf you dont want to wait for the full animation, you can now instantly claim your reward and jump back into designing patterns and fighting.
[/*]

[hr][/hr]

Gameplay & balance imports, artifacts, achievements

Fixed a bug with importing patterns\nFor some players, the pattern import system could behave incorrectly. It should now work reliably.\nHuge thanks for reporting and helping debug this issue: [dynamiclink href=\"https://www.twitch.tv/potomac_89/\"][/dynamiclink]
[/*]
Improvements to several artifacts in the shop\nA few artifacts didnt fully match their descriptions or their effects were unclear. I went through their configuration, logic, and text they should now feel more consistent and more useful in specific builds.
[/*]
Fixed and adjusted several Steam achievements (descriptions + game logic)\nDuring Steam Fest I changed one thing: the player now receives basic equipment (laser, nuke, and repair drones) that can be used during gameplay (via hotkeys or by clicking UI).\nSide effect: some of these items could not be bought again, which caused confusion with certain achievements.
[list]
I updated the logic behind a few achievements.
[/*]
I also changed some descriptions one achievement now clearly says:\nBuy this or equip in the store\nso it reflects how it can be unlocked.
[/*]

[/*][/list]

[img src=\"https://cdn.cloudflare.steamstatic.com/steamcommunity/public/images/clans/45651685/ef49a52610da4239f96d5dc21530f5f17e8090f2.gif\"][/img]

[hr][/hr]

Technical improvements display, audio, saves

Fullscreen / Windowed mode fixes\nFor some players, the game could start in windowed mode by default.
[list]
Fixed how display mode is saved and loaded.
[/*]
Your display preferences should now be respected more reliably.
[/*]

[/*]

Audio module (sound & music) fixes\nIn rare cases, even after lowering the volume in options, audio could reset to default values.

Fixed initialization and saving of audio settings.
[/*]
Once you set the volume, it should now stay that way across sessions.
[/*]

[/*]

Save-system improvements

Improved how various data is written and loaded (settings, progress, configurations).
[/*]
Reduced the chance of rare situations where certain preferences could be lost between runs.
[/*]

[/*]

[/list]

[img src=\"https://cdn.cloudflare.steamstatic.com/steamcommunity/public/images/clans/45651685/37e735bab22432e817474128cdf4f150c4c1785c.gif\"][/img]

[hr][/hr]

Preparing for future content emitters and training

Emitter properties: SIMPLE / ADVANCE (preparation)\nIn the code, Ive laid the groundwork for distinguishing between simple and advanced emitter modes.\nThis will make it easier to:
[list]
offer a more accessible mode for new players,
[/*]
and deeper, more complex options for players who love fine-tuning their patterns.
[/*]

[/*]

New TUTORIAL / TRAINING mode (preparation)\nIm also preparing a TUTORIAL / TRAINING mode that will:

guide new players through how emitters work,
[/*]
let you test your patterns in a controlled environment,
[/*]
help you understand the mechanics before jumping into full chaos.
[/*]

[/*]

[/list][hr][/hr]

Other minor fixes

Various small UI tweaks, cosmetic changes and internal clean-up that arent as visible, but help overall stability and feel of the game.
[/*]

[hr][/hr]

Thank you to everyone who:

reports bugs,
[/*]
writes reviews,
[/*]
sends me screenshots and pattern ideas,
[/*]
or simply plays and recommends the game to others.
[/*]

Key changes

Sandbox improvements more control and better tools to test your patterns.
[/*]
Boss respawn in Sandbox train against all 14 bosses whenever you want.
[/*]

[/*]

SANDBOX training like in a lab

Boss respawn in Sandbox \nYou can now respawn bosses directly in Sandbox and train against each of the 14 unique bosses, with:
[/*]
their own strategy,
[/*]
unique attacks,
[/*]
distinct behaviour / AI.
[/*]

[img src=\"https://cdn.cloudflare.steamstatic.com/steamcommunity/public/images/clans/45651685/56e2511f8cb5b581f10a8b8989894d461e480875.png\"][/img]

Its a great place to learn the mechanics before Campaign or other modes.

[olist]

Sandbox fixes

Better stability and small UX improvements to make testing builds more comfortable.

[/*]

Note Auto-hide panel \nDue to a previous save bug you may need to re-enable the Auto-hide panel during wave option in Sandbox your previous setting may have been reset after this update.

[/*][/olist]

New enemy Berserker

New enemy type: Berserker
[/*]
Can destroy your bullets.
[/*]
Is very durable, so you cant just click through it with anything.
[/*]
Is meant to break overly comfortable builds and force smarter pattern design.
[/*]

Emitters and clarity of information

New emitter option: auto target \nTowers can now automatically rotate towards enemies, similar to tower-defense games. \nSimply enable auto target in the emitter properties any pattern can now target enemies if you want it to.
[/*]
Improved SPREAD indicator \nYou can clearly see the main projectile and the directions where additional projectiles will be fired. \nDesigning and debugging complex spreads is now much more comfortable.
[/*]
Gamepad and keyboard improvements
Small input tweaks to make controls more consistent and predictable.
[/*]

SPREAD better readability

The new SPREAD indicator shows:
[/*]
how many projectiles will be fired,
[/*]
in which directions,
[/*]
and the main projectile highlighted in yellow.
[/*]

[img src=\"https://cdn.cloudflare.steamstatic.com/steamcommunity/public/images/clans/45651685/e51d7f32042465bf7dc67fd091bbdab9ebacb7a5.gif\"][/img]

New emitter option: auto target

Emitters can now automatically rotate towards enemies. In the \"Movement\" tab you just need to enable \"auto target\":

the tower automatically targets nearby enemies,
[/*]
any pattern can become a halftower-defense setup without changing other parameters,
[/*]
now every pattern matters,
[/*]
useful option for beginners,
[/*]
can be combined with homing bullets, standard bullets, etc.,
[/*]
the option is completely optional if you want, you can still play with manually set shooting directions.
[/*]

[img src=\"https://cdn.cloudflare.steamstatic.com/steamcommunity/public/images/clans/45651685/37e735bab22432e817474128cdf4f150c4c1785c.gif\"][/img]

Campaign and UI

Wave trigger fix \nFixed an issue where pressing Space could start a new wave while dialogues were still on screen. \nDialogues are now safer from accidental wave starts.\n
[/*]
Difficulty selection window \nThe game now asks for the difficulty level when you first enter the menu and informs you that it can be changed at any time in the options. \nYou can also tick Dont show again.\n
[/*]
Survival Dont show this window again \nThe Survival window now has a Dont show this window again option so you can get back into the game faster on subsequent attempts.
[/*]

Localization over 90 languages

Updated and improved translations for over 90 languages.
[/*]
New Sandbox options, difficulty and Survival windows are localized.
[/*]
Small fixes to text consistency and readability in the interface.
[/*]

Whats next editor, new modes and CODEX

This update is not the end Im working in parallel on more features that will be added to the game.

SIMPLE / ADVANCED two editor modes \nI want the pattern editor to be:
[/*]
friendly for beginners a simpler view / SIMPLE mode,
[/*]
powerful for advanced players full access to all sliders in ADVANCED mode.
[/*]

Goal: less overwhelm at the start and more power for players who like tweaking details.

[olist]

New ranked mode NO LIMIT \nIm working on a separate ranked mode called NO LIMIT, where:

[/*]

there will be no limit on the number of projectiles,

[/*]

there will be no limits on emitters.

[/*][/olist]

[img src=\"https://cdn.cloudflare.steamstatic.com/steamcommunity/public/images/clans/45651685/bd9f2ed3a779bea966fba8c0d0f06b9b52e0357c.png\"][/img]

Limits in the main game exist because its not possible to reasonably balance an unlimited number of projectiles.

\nThats why NO LIMIT will be a separate ranked mode pure madness, with no promise of balance, but with a leaderboard for those who want to squeeze absolutely everything out of the engine.

[olist]

CODEX enemies, planets, game world \nIm preparing a CODEX, which will include:

[/*]

descriptions of enemies,

[/*]

information about planets,

[/*]

other elements of the world you encounter in the game.

[/*][/olist]

The CODEX is meant to be a place where you can calmly read about what just destroyed your tower.

New tutorial / training mode. I want to add a separate tutorial / training mode, which will:

[olist]

introduce you step by step to the basics of the editor,

[/*]

let you practice specific mechanics (SPREAD, auto target, bosses),

[/*]

be good both for new players and for those returning after a break.

[/*][/olist]

More tooltips and hints. Im also planning more tooltips:

[olist]

more short descriptions for sliders and options,

[/*]

better explanations of what parameters do in the editor,

[/*]

subtle hints in places where questions most often appear.

[/*][/olist]

Thank you for playing Pattern Survivors, supporting a one-person studio and sharing your feedback.

[/*]
Polish: animations, VFX, minor UI tweaks.

Steam will do it automatically; if not click Verify integrity of game files in Settings, or restart the game.
[/*]
The demo has this patch too you can quickly try the new knockback without touching your saves.\n
[/*]

GIF tip\nUse the WALL DEFENSE preset, enable knockback, trigger a high-density wave 58 seconds and youre set. A perfect evening pattern.

Thanks for the feedback and reports they help me ship these mini-revolutions faster. Got an idea for the next preset or a quality-of-life tweak? Hit me up. Airem (solo dev)

Important Information About the Upcoming Update

Hello,\n\n[img src=\"https://cdn.cloudflare.steamstatic.com/steamcommunity/public/images/clans/45651685/ab0ecbda462e7d415d486fdf2ffc5669a34a1886.png\"][/img]

A major technical update is on the way the game will soon switch to a new framework.\nThis is a big step forward (performance), but please note that it may cause issues with existing progress.

[u]Click on the settings in the Youtube video and set it to HD 1080p60:[/u]

[hr][/hr]

What does this mean?

The new demo will include as shown in the preview image an option to import your old save game.\n\n[img src=\"https://cdn.cloudflare.steamstatic.com/steamcommunity/public/images/clans/45651685/0f6b1d3ad0c563446785a04fa7c8215343fa87af.png\"][/img]

[/*]

\\[]Option 1: Import your old save and continue where you left off.\n\\[]Option 2: Start fresh in the new version if you prefer a clean slate.\n\nYour old save files will remain fully accessible in the current demo version,\nand you can import them anytime later.\n\n

[hr][/hr]

New Mode: TOWER DEFENSE CLASSIC

\nIm also finishing work on a new mode that was not available in the previous demo.\nIts called TOWER DEFENSE CLASSIC, inspired by classic tower defense games.\n\n

Enemies move along a fixed path.\n
[/*]
Defend your tower by creating attack patterns.\n
[/*]
This mode is slower, more predictable, and perfect for beginners.\n
[/*]

\nThank you all for your support and for testing the demo every bit of feedback helps improve the full release! \n\n

Pattern Survivors Update 1.1.2

Hello,

[img src=\"https://cdn.cloudflare.steamstatic.com/steamcommunity/public/images/clans/45651685/bd9f2ed3a779bea966fba8c0d0f06b9b52e0357c.png\"][/img]

This update brings a set of technical improvements, bug fixes, and deep engine optimizations for PatternBULLET2D Engine by Airem.\nPerformance and stability have been improved across all devices especially noticeable on low-end hardware.\n\n

[hr][/hr]

Changes & Improvements

\n Online / Offline Leaderboard System\n When the player finishes a run with an active internet connection, online rankings are now displayed automatically.\n The system detects the connection and switches to online mode when available.\n If no connection is found, it switches to local ranking, which can later be manually updated by switching from online to local.\n Local scores are not overwritten unless the player chooses to update them.\n\n

[hr][/hr]

\n Improved Streaks.js System\n Fixed rare logic issues with combo and multiplier tracking.\n Smoother score progression and better streak handling during long sessions.\n\n

[hr][/hr]

\n Major Engine Performance Boost (PatternBULLET2D)\n Optimized logic and rendering loops.\n Improved memory management and particle caching.\n Average framerate boost on low-end systems: +2550%.\n Faster loading times and smoother transitions between levels and effects.\n\n

[hr][/hr]

\n Bug Fixes & Stability\n Fixed minor logic bugs in collision and visual systems.\n Improved fullscreen/window switching behavior.\n More reliable save-state system across campaign and survival modes.\n\n

[hr][/hr]

\nMade with care solo, line by line, pixel by pixel. \nThank you for playing and supporting Pattern Survivors.

Changelog (all updates)

First update 1.1.1 - Online leaderboards for demo and full version

Hey everyone!

Chaos never sleeps and neither does Pattern Survivors. \nUpdate 1.1.1 brings dozens of fixes, optimizations, and small improvements that make the gameplay smoother, faster, and more responsive both in the full version and the chaos-driven demo edition.

[img src=\"https://cdn.cloudflare.steamstatic.com/steamcommunity/public/images/clans/45651685/0a527daac998d759eb407f0fa6e929247b01808c.png\"][/img]

[hr][/hr]

Cross-Platform Update

This update covers all versions of the game: Windows (32 & 64-bit), Mac (64-bit) and Linux (64-bit). \nEach platform received engine tweaks, better memory handling, and lower CPU/GPU load during heavy on-screen chaos.

Ive also fixed an issue with the Steam Overlay that prevented it from launching on certain setups. \nIt should now work correctly across all platforms (if not, please report it in the support thread).

[hr][/hr]

Improved PatternBULLET2D Engine

My custom bullet engine has been optimized for massive waves and hundreds of active units. \nExpect smoother motion, more precise collisions, and better effect management while keeping that distinctive Pattern Survivors style.

In short: more bullets, fewer FPS drops.

[hr][/hr]

Unit & Projectile Fixes

[olist]

The Shielder unit was reworked for performance; its shields and animations should no longer cause frame dips after wave 5.

[/*]

HOMING projectiles now have smoother motion and smarter target tracking.

[/*]

General AI and performance improvements for other units.

[/*][/olist][hr][/hr]

Online Leaderboards (Steam)

From now on, the demo also supports online leaderboards, letting players compete on the same terms as the full version.

To keep things fair, leaderboards are separated demo and full edition each have their own score tables.

Every death, every wave, every save it all counts now.

[hr][/hr]

Localization & Assets

This patch updates 30 languages (more coming soon), covering both in-game text and Steam store pages.

Dozens of translations were refined for clarity and formatting; graphics, logos, and library art were also refreshed.

[hr][/hr]

Other Fixes & Optimizations

[olist]

Removed leftover internal test code (code cleanup pass).

[/*]

Minor sound and effect polish.

[/*]

Font alignment fixes in several languages.

[/*]

More stable save behavior in Sandbox and Survival modes.

[/*][/olist]

Its not a huge content update, but a solid foundation for whats coming next. \nPattern Survivors enters a stage where every frame, every bullet, and every line of code matters.

[hr][/hr]

Thank you to everyone playing the demo, sending feedback, and supporting the project \nThe chaos is just getting started.
