Open your senses to the misty mazes of Impostor Assassin Online! Grab your ninja gear, step up on the platform, and focus on your enemy's steps! Stay out of sight, take the enemy groups down one by one, and collect all the stars to complete top-secret missions with high scores!

Wear your ninja costume and close the lights; we are going on a top-secret mission to collect stars. Let's see how many enemies you can take down without getting caught! Dressed like them, you can slip into the enemy team, but do not forget whose side you are on! Hold on to your weapon, build a strategy for the room, and sneak behind the enemy with your lightest steps! Each room comes with its unique challenges; some will be dark, while some will not give you any place to hide. The enemy's movement patterns are smarter than you think, so you must trust your ninja instincts instead of retrying the same plan repeatedly. Defeating an enemy will draw attention to you, making it easier for the other enemies in the room to follow you. Lure them to the opposite corner of the room and hunt them down! Unlock new weapons with gold coins and upgrade your attacks!
