The survival of the human race lies entirely in your hands. Space Siege puts you in the shoes of Seth Walker, a crew member on the Armstrong - the only evacuation ship to survive a massive alien attack against Earth. As the aliens descend upon the Armstrong, Walker must fend off the extraterrestrial threat using his wits and weapons. To help his cause, he can choose to augment his body, and create a robotic sidekick with a variety of cybernetic upgrades available throughout the Armstrong - but with each mechanical improvement, he becomes more machine than man. In this spectacular sci-fi adventure, will you risk your own humanity to save the human race?
