Underlight is a fantasy multiplayer online role-playing game. It was Lyra Studio's first product and launched on MPlayer.com in March 1998. The game is currently managed by KoiWare and was released on Steam in December 2018. The game currently operates on a free-to-play model, but players are able to purchase 'Pmare credits' allowing them to play as powerful monsters instead of normal characters. Gameplay Underlight is a first-person graphical MUD. Players move around the world using the graphical interface, with speech, emotes, and feedback from the environment reported in a chat window. The game world is divided into a series of rooms, many of which spawn items or monsters regularly. Multiple rooms make up a plane, each of which has its own theme and access requirement. Mechanically, planes are identical but it's typically easier to communicate with players on the same plane than on different ones. Characters specializations fall into four focuses, each selected at character creation, which determine the skills they learn as they level up. Gatekeepers, aligned with the element of Willpower, are a melee-oriented focus, having the strongest basic attacks and the ability to block off doorways. Dreamseers, aligned with Insight, have the most potent ranged arts and are the best at using items. Soulmasters, aligned with Resilience, are a defense-oriented focus with the ability to shield and heal others. Fatesenders, aligned with Lucidity, are regarded as tricksters and have the ability to inflict various status effects on players and monsters alike. Aside from defeating monsters, characters can gain experience by completing tasks granted to them by other players. Skills also have levels which have a chance to increase each time the skill is used, making them slightly faster and more powerful. Progression for both character levels and skills is restricted every tenth level until the character completes a task. These are typically assigned by another player who has been granted the title of 'teacher', which is in turn granted by a game master. Roleplay in the game is strictly enforced and the game is notable for lacking any non-player characters other than most monsters. The most powerful monsters are also controlled by players or game masters and have the same abilities as characters, being able to move between rooms, trade items, and converse, although their speech is filtered through a basic cipher for any characters listening, and vice versa. Characters also have the ability to join
