Field Guide
How Spectrum Siege works
The song is the director. Louder sections, harder beats, and sharper treble spikes change enemy mix, weapon spread, boss pressure, and the pace of the whole arena.
Controls
- Move: `WASD` or arrow keys. During boss zoom-out you can move anywhere visible on screen.
- Aim: The ship always faces the mouse. Left click holds primary fire in any direction.
- Special: Hold right click to charge the special weapon, then release to fire it.
- Dodge: Tap `Shift` for a fast half-second burst with eased in and eased out movement.
- Bomb: Hit `Space` to trigger a screen-clearing super bomb.
- Pause: Hit `P`. `ESC` exits fullscreen and pauses the run in mission control.
Song Driver
- Energy: Louder, denser sections increase overall threat and projectile volume.
- Bass: Low-end pressure favors bruisers, heavier barrages, and wider battlefield shock.
- Treble: Sharp highs push faster enemies, quicker fire, and more violent movement.
- Beats: Strong beat spikes trigger surges, pressure waves, and harder incoming windows.
- Progress: Later song sections unlock tougher enemy mixes, more elites, and bigger boss fights.
- Analysis: The stats panel estimates pressure, volatility, and likely difficulty before launch.
Enemy Families
- Pulse Drifter: Curved entry swarms that establish the tempo and flood lanes.
- Bass Bruiser: Slow heavy hulls with deep-bass soak and punishing volleys.
- Needle Sprint: Treble-fed dash hunters that stab through open space fast.
- Resonance Splitter: Midrange units that fracture into shard pressure later in the song.
- Sync Mine Layer: Trap ships that seed the arena with beat-reactive mines.
- Chorus Sentinel: Shielded late-run elites that turn wide-open sections into rotating fire walls.
Power-Ups
- Primary / Special Swap: Changes your current weapon family mid-run.
- Primary Power / Special Power: Stacks projectile count, damage, size, and speed with no cap.
- Hull Repair: Restores lost hull so you can survive longer boss phases.
- Shield Boost: Adds a front-loaded defensive buffer before hull takes damage.
- Score Multiplier: Raises scoring and lets strong runs scale even harder.
- Super Bomb: Adds another emergency full-screen clear.
Bosses & Scaling
- Warning: A boss warning flash hits before warp-in, then the camera zooms out for the fight.
- Families: Any enemy family can roll a boss, and each tier escalates health, weapons, and pressure.
- Threat Scaling: Bosses estimate your current run strength and scale to match it.
- Threat Rating: The boss HUD bar shows a live threat multiplier for that encounter.
- Recovery: After the boss dies the camera closes back in slowly, guiding you into the tighter field again.
