About BIRDCAGE
BIRDCAGE is a fast‑paced vertical scrolling shoot‑em‑up that mixes 90s arcade intensity with modern storytelling. Players pilot the experimental RADON gunship HALCYON, wielding a wide shot, focus shot, and the unique SWORD weapon. The game unfolds in a divergent human future, pitting the Moon‑based SELENE faction against RADON’s space colony CAGE. Across six story stages and several score‑focused modes, players chase high scores while uncovering a sci‑fi narrative about the WORLD‑EGG.
01 / THE GUIDE
Weapons and Shooting Mechanics
HALCYON offers three offensive options: a wide shot for covering area, a focus shot for precision, and the SWORD, which serves as both main attack and defensive tool. The SWORD’s dual role adds tactical depth to the vertical scrolling combat. The combination of these weapons lets players adapt to enemy patterns, switching between spread fire and concentrated damage as needed.
- Experiment with alternating wide and focus shots to manage dense enemy swarms.
- Use the SWORD defensively when enemy projectiles converge on your ship.

Available Game Modes
Story Mode spans six stages with mid‑bosses, stage bosses, and narrative interludes, delivering the full plot. Arcade Mode strips the story for quicker, score‑driven runs. Score Attack challenges players to earn the highest score within a timed limit as enemies spawn endlessly. Each mode caters to different playstyles: narrative immersion, pure arcade scoring, or timed skill sharpening.
- Try Arcade Mode to practice boss patterns without narrative interruptions.
- Use Score Attack to gauge improvement by comparing timed scores.

Retro Audio and Visual Design
BIRDCAGE emulates early 3D aesthetics using sprite scaling, pre‑rendered backgrounds, and limited textures, echoing 90s arcade and anime visuals. The soundtrack blends 90s music hardware sounds with modern synthesis, offering over an hour of dynamic music and hundreds of bespoke sound effects. Retro‑styled voice acting for stage bosses further reinforces the nostalgic atmosphere while supporting the sci‑fi story.
- Adjust volume controls to balance the retro music with modern sound effects.
- Listen for boss voice lines to anticipate upcoming attack phases.

Factions and Narrative Premise
Humanity has split into two factions: SELENE, controlling the Moon and remnants of Earth, and RADON, ruling the space colony CAGE. Mother ROENTGEN leads the RADON Daughters, who commission GENOME Control to create the WORLD‑EGG, a weapon intended to end Earth’s reign. The pilot awakens in HALCYON within CAGE, hearing a voice urging the destruction of the WORLD‑EGG, setting the stage for the game's conflict.
- Pay attention to narrative interludes for context on faction motives.
- Consider how the pilot’s voice aligns with the overarching goal.
