Go inside a huge military base and destroy all the enemies that get in your way. Your task is to look both ways and not be in the beams of spotlights of flashlights. If you are tracked down, they will instantly launch an attack. And, since the level of your armor leaves much to be desired, it will not be enough for a long time. Therefore, justify your title, remain an invisible hunter and try to destroy everyone, collecting keys and various banknotes along the way. Do not be under the gun and reach the end. Good luck in the game!
