As humanity explores space, they encounter an evil and very powerful race called the Kerak. The humans have no chance against the race and run back to Earth. A fatal mistake as on June 10th 2202 the Kerak enter the orbit around the planet with a fleet a hundred times bigger than anything humanity could ever hope to defeat. So in a last resort they fill up their gigantic colony ships and try to escape through the blockade to found a new home.
Several weeks later, Earth is no more. The Kerak pulverized it with the power of their several hundred orbital strike cannons. And all colony ships have been destroyed during their run. All ships? No! Although the Armstrong was also boarded by Kerak, they were able to make the jump into hyperspace. But as robotic specialist Seth Walker awakes from the frozen sleep, most humans on board the ship have been killed and the Kerak are doing everything to also destroy those who remain. Now the fight for the survival of mankind begins.
Space Siege is a hack ‘n’ slay RPG like Dungeon Siege set in a sci-fi universe. The player orders Seth around the ship with the mouse in a isometric view to find survivors and kill all the Kerak in his way. To defend himself against the hordes and hordes of enemies, Seth not only has access to a big arsenal of weapons ranging from a sword to machine guns and rocket launchers. But he can also use abilities. These abilities cost energy on activation but either provide a greater punch to Seth’s attacks or give him a temporary boost. Early in the game Seth even finds a companion in form of the robot HR-V or “Harvey” to aid him in battle. Seth can give Harvey commands like “attack this” or “move there” and even upgrade him at the many workbenches in the game. At these Seth can also upgrade himself, his weapons and produce additional items like grenades or medi-packs.
For any of these actions Seth needs parts which either drop from enemies or can be found in boxes scattered around the ship. So instead of looting more powerful items, Seth only finds parts to upgrade his existing load out. In addition Seth also doesn’t gain any levels. The skill points for the two skill trees combat and engineering are automatically awarded at pre-defined points in the game. And to add a moral dilemma to the game, Seth has the choice of implanting cybernetic parts in himself. But although this can greatly improve his screens and give him access to additional abilities, it will also decrease his humanity level. So the player needs to choose of how much of a mindless killing machine he wants to become in order to defeat the Kerak. The choice influences some aspects of the game including the ending.
If the player is sick of Harvey and wants someone with a little more brain than brawn on his side, he can create a coop-multiplayer campaign for up to four players. The coop-campaign also includes special missions, that aren’t part of the normal single player campaign.
