As humans are fleeing the planet during a massive alien attack on Earth, only one of five evacuation colony ships escapes intact before Earth is completely obliterated by the attacking aliens. In Space Siege, you take on the role of Seth Walker, a combat engineer aboard the Armstrong (the lone surviving ship). Your objective is to protect the human race from being annihilated by this unknown alien species. Ultimately, you must make a horrific choice: will you sacrifice your humanity to save the human race?
At your disposal will be an arsenal of futuristic weaponry and armor, cybernetic upgrades, and a robotic partner that you can customize and command. Space Siege will also feature a single-player campaign that takes place across the vast confines of the Armstrong, a separate mission-based multiplayer campaign, character-building gameplay elements and a storyline that asks: What does it mean to be human?
- Tactical Combat Action – Outsmart your enemies by setting up ambushes, dodging attacks, ducking behind cover, and using any of the multiple special abilities available to you.
- Multiple Gameplay Paths – Define your game experience with the decisions you make. Will you remain truly human in the face of insurmountable odds?
