Zarya - 1: Mystery on the Moon

We thought we were alone in the universe, but after receiving a strange signal from the dark side of the Moon, everything we thought is now under question. We need a team of exceptionally talented specialists to venture out and unravel the darkest secrets known to humankind. Zarya-1 is an interactive fiction game that takes place on the far side of the Moon. You are tasked with supervising a team of four specialists to locate and explore the source of a mysterious signal. Your decisions will matter -- but the consequences aren't always clear and sometimes disaster will happen. Every choice you make will give you a slightly different perspective on the events that will unfold -- and with it, another grain of the truth.
