About the Game


"I remember getting the call vividly. I was trying to finish up for the day, but a stack of paperwork was keeping me late. To be honest, I was also looking for reasons not to go home. My phone rang, I answered it, and the director of the institute was talking, albeit disjointedly, about something that had turned up in a recent survey of The Sirena Deep."



Explore a mysterious, abandoned underwater facility at the bottom of the Mariana trench. Who built it? What was it used for? Perhaps you will find answers, or perhaps the answers will find you.



You can play through The Sirena Expedition in about an hour. However, there may be some hidden content, for those willing to look for it.
