Pattern Survivors: Bullet Hell

Pattern Survivors: Bullet Hell is an action roguelite in which you operate a cosmic tower and create its attack patterns to survive waves of enemies. The Patterns appeared suddenly; they are neither alien nor human, but fundamental. As the Tower Operator, you adapt, build attack formations and uncover the mystery of the Patterns.

Create attack patterns

You place emitters and adjust their angles, speeds, rotations and spread to design bullet formations. You can also choose ready-made presets, use a random layout generator and save patterns as JSON files. Each wave tests your creativity and reflexes as you upgrade your tower and face cosmic threats.

Game modes

Choose between a story campaign and several other ways to play:

• Campaign: Follow a storyline with dialogue choices, main and side missions, 14 unique bosses, diverse enemies and the mystery of the Patterns to uncover. It includes an intro and ending scenes.
• Survival: Face endless waves of increasing difficulty. You start with no abilities, and global leaderboards track how long you survive.
• Sandbox: Experiment freely with builds and patterns, with God Mode available.
• Quick Run: Play a 10–20 minute session, with global leaderboards.
• Tower Defense: Defend against enemies moving along set paths as the difficulty increases each round. The final stage becomes an endless survival battle.

Upgrade your tower

The tower shop offers towers, artifacts and abilities to purchase. You can collect Quantum Data Cores, scan planets and hunt anomalies. Abilities include nuclear bombs, drones, deflecting shields and time slowdown. Active tools include mines you can place anywhere on the battlefield, support ships, and units for flanking or ambushes; combining these options can change how you approach each fight.

Save and replay

You can save and quit at any time, then resume with the bullets, enemies and abilities still in place. Random upgrades and the pattern system make each run different.
