KAIKAN: A Thrilling Vertically Scrolling Shooter

Prepare for intense aerial combat in KAIKAN, a vertically scrolling shooter where you'll pilot your fighter through waves of relentless enemies. Skillfully dodge enemy fire and unleash devastating attacks to dominate the skies and achieve a high score.

Master the Scoring System

Destroying enemies unleashes valuable bonus items. Collecting these items increases your item rank and boosts their scoring value. Strategically manage your risk and reward – missing an item results in a [PENALTY] rank decrease, requiring careful collection to recover. Utilize the unique mechanic of attracting and releasing items by controlling your shot button.

Harness the Power of Bombs

Collecting bonus items also charges your bomb gauge. A full gauge grants you access to powerful bombs. Unleash a bomb to convert enemy bullets into bomb bonus items and deal massive damage. Bombs provide a high score bonus and increase the on-screen counter, but don't increase the bomb gauge.

Boss Battles and the BOSSMEDAL

The on-screen counter is crucial during intense boss battles, acting as a timer that directly influences boss and part score. Wrecking bosses will net you BOSSMEDALs, which are used as a counter for the final boss showdown. Items collected during boss destruction replenish your bomb gauge.

Choose Your Aircraft, Master Your Playstyle

KAIKAN features 6 distinct aircraft, each with unique weapon characteristics and behaviors that change when moving at low speed. Experiment with each type to find your perfect aerial combat style:

typeA: Napalm that explodes on impact.
typeB: Wide Shot for sweeping attack range.
typeC: Homing Missiles that track enemy targets.
typeD: Fire to blanket the screen.
typeE: Blast which emits high power.
typeF: A protective Ball that rotates and clears enemy bullets.

This updated version of KAIKAN delivers significant improvements including: STEAM ranking, performance enhancements for all aircraft types, a widened screen, a mini-map showing off-screen positions and aircraft placement, and a revamped counter system for true boss battles.
