Space Siege is an action role-playing game with an emphasis on action. You only find a handful of weapons and cybernetic parts, and there aren’t any other pieces of equipment. You don’t gain any levels or experience points, but you sometimes find “upgrade materials,” which you can use to purchase upgrades or supplies (such as health packs and grenades), and you sometimes receive skill points for completing quests, which you can spend on the game’s 29 skills. And the campaign is linear, with almost no meaningful dialogue or choices or story development (and the minimalist story, such as it is, ends up mostly being a rip-off from I, Robot, but I guess if it’s okay for Mass Effect to “borrow” from Frederik Pohl, Space Siege can borrow from Isaac Asimov).
