Space Siege

Space Siege takes place on a massive space colonization ship under attack by an alien foe that has annihilated the planet Earth before the game begins. Chris Taylor has described the plotline as introducing a moral dilemma regarding human cybernetic augmentation. Players have the choice to replace body parts with cybernetically enhanced components throughout the game, to more effectively counter the alien threat at the sacrifice of their humanity. However, the greatest bonus that comes near the end of the game is only accessible if the player remains human. Choosing the "pure path" allows players to upgrade their robotic sidekick and powered armor.
