<p align="justify">Noiseless Steganography is a steganography algorithm that does not use or produce noise which can expose the existence of the embedded message to other parties. Nostega uses uncertain elements in media that is seemingly legitimate and it’s validity cannot be confirmed, such as data in graphs or text produced by an event summary generator. <br /> <br /> <br /> One of the potential media for Nostega methods are role-playing game (RPG) which is a game genre where players role-plays as various characters and go on adventures as the character. RPG is used because it has various uncertain elements such as freedom of the player’s actions and value calculation that the player does not comprehend (black box features). <br /> <br /> <br /> In this research the game Empyrean Campaign using the Flare open source engine is used as a case study of the Nostega method RPGStega. Based on the Nostega architecture parameters which are character attributes, damage values, and item attributes as well as a message encoder to transform message into the corresponding form the parameters is defined and implemented. A support application is also build for extracting the embedded message from the game as well as communication protocol and covert channel that defines the interaction between the sender and the receiver. <br /> <br /> <br /> Using a survey that implements the game developer and tester communication protocol and covert channel, it is found that the RPGStega method is indeed noiseless and is a Nostega method. It is also found that some parameters can hold an infinite amount of message but with the drawback of increasing numbers of characters the player has to encounter which will burden the player. Moderately, the implementation can store around 100 bytes of message. <p align="justify">
