Space Siege takes place in the confines of the Armstrong, one of the few remaining colonization ships carrying the last bastions of human civilization after a devastating attack on Earth from an unknown alien race. Players will take the role of Seth Walker, a robotics specialist suddenly thrust into a struggle to save humanity from extermination. As the adventure progresses Seth is offered opportunities to sacrifice pieces of his humanity for cybernetic upgrades that will assist him in his mission to preserve the human race. But what price will he pay to save his own humanity? Only the player can decide Seths ultimate fate.
Incorporating innovative cybernetic augmentations into its storyline, Space Siege explores the dilemmas faced while keeping ones humanity in the face of adversity. Cybernetic augmentations can be performed on every part of Seths body. On the extreme end, players will be able to outfit Seth with cybernetic upgrades that will leave little or none of his original humanity intact. But this choice comes with the risk of alienating Seth from the people hes trying to save. Players can also insist on preserving Seths humanity by not using upgrades, instead forging ahead clearing the Armstrong of its alien invaders with natural human ingenuity and strength. Such a decision will increase the difficulty of completing his mission of uncovering and eliminating the alien menace thats bent on destroying the human race.
Space Siege features a dynamic storyline based upon the decisions the player makes throughout the course of the game. Based upon the cybernetic modifications the player chooses to make on Seths body, NPCs will react and interact with the player differently and, ultimately, different story resolutions will be reached. Space Siege will feature a separate immersive co-op multiplayer mode allowing up to four players to create and experience a completely unique mission structure.
