The war officially ended when the galactic megacorporation United Mining claimed an overwhelming victory, but they were unable to suppress the rampant piracy of lumen, so they passed regulations to allow any person who discovers lumen reserves to claim its mining rights, so long as they pay a percentage of the profits to United Mining. As he activates an ancient gate, he begins to think back on the woman he made his promise to, Eda, and the adventures they shared together decades ago.īack then, Thousand Peaks was recovering from the Lumen War, a 20 year conflict that involved numerous factions from across the galaxy, fighting over a valuable resource known as Lumen, which could be mined from the planetary system's asteroids. Players take control of Jun Lee, an elderly adventurer who returns to an unnamed asteroid, claiming that there's an old promise he has yet to fulfill there. The game takes place in the fictional planetary system Thousand Peaks. Once the puzzle is solved, players will gain access to the inner areas of the lumen cave. The goal is to tune the starsong, so the equalizer bars overlap with the inscriptions. Once players find the correct starsong, the game will zoom in on the circular surface, and start playing the chosen starsong, with an equalizer interface appearing on top. These contraptions have circular surfaces covered in inscriptions, and must be activated with specific starsongs in order to open up. Lumen caves contain contraptions that block off areas of the environment. The environment also includes various contraptions that players must solve to progress. Players can control their character to explore the environment, which will present points of interaction that reward players with lore, or resources. When players visit a lumen cave, the game's perspective is changed to a 2.5D side-scrolling view. Once the puzzle is solved, players will be rewarded with a starsong that reveals a lumen cave. The goal is to overlap the correct orb with the center, which can be determined by changes in the character's singing voice. Using the center as a pivot, players can rotate the orbs in any direction. Doing so will trigger a puzzle sequence where the player character starts to sing in the center of the screen, while orbs of light representing sources of starsongs surround her. Any one of the activities may also trigger encounters much like the ones during space navigation.ĭuring space navigation, players will be occasionally prompted to search for starsongs when they're within range of lumen caves. Each location also has a menu of activities players can engage in, which includes visiting a shop, visiting various locales, or searching for resources. When players reach a location, they get a view of its appearance, and backstory that reveals the history of Thousand Peaks. Some locations, such as lumen caves, are hidden until players find its starsong, sound patterns that originate from the hidden locations. Flying to any location requires fuel, and may trigger situational encounters where players have a chance to gain rewards, or lose resources. In space navigation mode, players can move a crosshair along a top-down map of Thousand Peaks, and select which location to visit. Gameplay alternates between dialogue, exploration, resource management, and puzzle-solving. Reaching certain locations during their journey will advance the story, prompting players to find their next destination. In OPUS: Echo of Starsong, the player's main goal is to fly their spaceship across the planetary system Thousand Peaks, and find asteroids known as lumen caves.
