Play Wai Wai World (Japan) Online
You swap between Konami's weirdest characters—a tiny ping pong bot, a vampire hunter, a spaceship pilot—each with their own moves to tackle side-scrolling chaos. It’s janky at first, but slashing through enemies as the samurai or dodging bullet-hell crabs just clicks.
Game Overview
Wai Wai World is this weird, charming little NES game where Konami threw a bunch of their random characters into one adventure. You've got the guy from Gradius, the vampire hunter from Castlevania, and even the tiny robot from Konami's Ping Pong—all running, jumping, and shooting through side-scrolling levels together.
At first, switching between characters feels a little awkward, but once you figure out who's good at what (the samurai dude cuts through enemies like butter), it gets surprisingly fun. The levels are packed with Konami's usual weirdness—expect giant enemy crabs, floating platforms, and way too many tiny projectiles to dodge.
It's not the deepest game, but there's something oddly satisfying about watching these mismatched heroes team up.
