Ghost Ninja is a fast-paced 3D arcade survival game where you face relentless waves of enemy ninjas in a deadly arena. Your goal is simple: stay alive as long as possible while cutting through massive hordes using sharp reflexes and smart movement. Every second counts as the enemy swarm grows faster and more aggressive.

Between waves, collect gems dropped by defeated enemies to unlock upgrades, new weapons, and stackable abilities that can create powerful, unexpected combos. No two runs play the same way – you might focus on speed and dodging one run, then go full offense with heavy weapon builds the next. The 3D arena keeps combat tight and tense, rewarding players who stay mobile and think fast under pressure. Watch your positioning, avoid getting cornered, and prioritize high-value gem clusters when it's safe.

Ghost Ninja is a perfect pick for fans of roguelite arcade shooters, wave survival games, and single-player arena challenges. If you enjoy games like endless ninja survival, 3D arena combat, or upgrade-based roguelikes, this one will hook you fast. It runs directly in your browser with no download or install required, making it easy to jump in for a quick run or grind for a personal best. Play Ghost Ninja free online and see how many waves you can survive.
