The plot of Descent revolves around an alien computer virus that has managed to infect off-world mining robots. Players assume the role of a mercenary, hired to investigate the disturbance for the company and eliminate the alien threat.
And, as Rock, Paper, Shotgun points out, the original Descent will turn 19 tomorrow. While we'd like to make a big deal about it, Descent isn't old enough to enjoy a crisp Appletini on an Autumn's day like a real adult so therefore we can't be expected to take this milestone seriously. Hit us up when you're 21 years old, Descent.
