FIELD GUIDE / WORLD 01
Know the signal.
Choose your move.
Your goal
Clear three floors and defeat the Black Sun Arbiter on the final floor. Death ends the run, but a new descent lets you choose a different class and build.
How a run unfolds
Choose the marksman, mage, or warrior. Explore combat rooms, then search for treasure, shops, events, and the elevator. Defeat each floor boss to continue. Collect shells for purchases; nearby shells, keys, and health supplies are picked up automatically.
How to play
Move with WASD or arrows; aim and fire with the mouse. Dodge with Space, right-click, or Shift. Press E to interact, Q for your class skill, C for your device, and F to clear bullets with a blank. R reloads or gathers mana; M/Tab opens the map, B shows equipment, and Esc pauses.
Useful tips
Use cover and dodge through dense bullet patterns. Save blanks for emergencies, check weapon synergies with B, and confirm the next room on the map. Mobile play requires landscape orientation.
