Play Konami Collection 4 Online

Konami Collection 4 came out for the Game Boy, a Konami release that fit right in with the handheld's library of compact, focused games. It arrived during a time when developers were still figuring out how to translate bigger console ideas onto that small, green screen, and this collection was part of that experimental push.

You control a character moving through a series of side-scrolling stages, fighting off enemies and hunting for keys to unlock doors. The main goal is simply to survive from one screen to the next, clearing out enemies and avoiding environmental hazards. Two mechanics stand out: the screen-by-screen progression, where each new area is a self-contained challenge, and the methodical combat that requires you to learn enemy patterns. The pacing is deliberate, and the difficulty can be unforgiving if you rush. It feels like a careful, tense puzzle where every move matters.
