2016年，以敘事作為主體的 「OPUS: 地球計畫」推出，除卻榮獲Googleplay 全球編輯推薦，東京電玩展驚奇之夜八強入圍，作品更以驚人的速度傳播，成為公司的成名作品之一。
2017年，「OPUS: 地球計畫」突破300萬下載，同年九月推出系列作「OPUS: 靈魂之橋」，首週載量突破百萬，更於 Google 與Apple 榮獲雙平台編輯精選，"感動人心的故事，溫暖卻悲傷的氛圍與音樂" ，來自於不同媒體間，卻重複述說的這句話演繹了作品的精神，自此奠定了「OPUS」系列作的整體品牌路線。
2018年中，「OPUS: 地球計畫 」與「OPUS: 靈魂之橋」系列下載突破 850 萬套，同時間，「OPUS: 靈魂之橋」被日本法米通評選為總分35分，成為台灣第一款進入「白金殿堂」的經典遊戲作品。
Established in 2013, SIGONO (originally known as Team Signal) is an independent game development studio based in Taiwan known for its chart-topping OPUS series. It's co-founders, Brian Lee and Scott Chen, met during their time studying at Carnegie Mellon University in 2011. Throughout the course they worked on a number of prototypes, including 'Last Signal', a game that utilizes the Xbox Kinect's functionality. The title would eventually be acquired by Microsoft and become the studio’s namesake.
After releasing Castle Rider in late 2013 to moderate success, the studio began work on Hyper Square in 2014, which was released in April and would go on to win numerous awards. Throughout the second half of 2014, the studio worked on their third title, Earthworm Alchemy, which was released in early 2015.
In 2015, the studio decided to break away from fast-paced action and explore the medium further. We set out to create something that evoked a sense of wonder and warmth, and the result was OPUS: The Day We Found Earth. Since launch, OPUS' unconventional storytelling and gameplay has received highly positive and emotional responses from players, and numerous awards and recognitions.
In mid 2016, after the positive response we've received from OPUS, SIGONO began work on its newest project - OPUS: Rocket of Whispers. The new title aims to be a spiritual successor to the original OPUS, and will be set in the same world. Our goal is to make games that move and inspire, and we invite those who share this interest to join us.
