1980年代ゲームセンター完全再現
Free · Designed for iPad. Not verified for macOS.
The legendary Japanese retro arcade shooter has arrived! Experience authentic 1980s CRT scanlines, pure 8-bit synthesized audio, and thrilling space defense!
■ Relive the Golden Age of 1980s Arcades in the Palm of Your Hand
Stepping into a dim, buzzing arcade in the 1980s: authentic 8-bit chip tunes echoing through the room, and legions of alien invaders aligned on curved CRT glass. "Retro Alien Invader: 1980s" faithfully recreates that unforgettable tension and pure arcade thrill on your iPhone and iPad.
Authentic CRT scanlines, pure real-time synthesized audio, and marching pixel-art aliens descending upon Earth. Close your eyes, and you are transported back in time to the golden era of arcades.
■ Classic Gameplay & Flow
Slide your cannon left and right to unleash rapid fire against descending alien armadas.
Three distinct alien invaders: higher rows grant higher points. The fleet marches back and forth, gradually descending towards your line.
And remember—the fewer aliens remain, the faster they march! Do you remember the adrenaline rush when the final lone invader dashed frantically across the screen at breakneck speed?
Mysterious UFOs randomly cruise across the top. Time your shot perfectly to claim massive mystery bonus points!
Four defensive bunkers protect your cannon from enemy bombs, but degrade with each hit. Will you play it safe, or strike aggressively? That tactical choice is the true essence of classic arcade gaming.
■ Two Modes: NORMAL & HARD
【NORMAL Mode】 A faithful recreation of the original retro invasion gameplay. Perfect for arcade veterans reliving memories and newcomers alike.
【HARD Mode】 Aggressive enemy barrages with double bullets, faster march speed, and higher UFO appearance rates. Bunker durability is reduced—only true arcade masters can survive!
■ Dedicated CRT Arcade Presentation
Authentic CRT scanlines and subtle corner vignette replicate the tactile feeling of vintage arcade monitors. From title screen to Game Over, the retro atmosphere never breaks.

Every sound wave is procedurally generated in real time using AVAudioEngine: ・Laser Shot: High-to-low pitch sweep ・Alien Explosion: Crisp noise burst detonation ・Player Explosion: Low descending shockwave ・Alien March: Rhythmic tempo-synced beats that accelerate automatically ・UFO Siren: Authentic vibrato high-frequency tone ・Wave Clear: Rising C-E-G-C celebratory arpeggio ・Retro BGM: Classic 8-note driving electronic bassline
