It's almost like they wanted to leave the player constantly in control of the character, for the sake of immersion, but didn't trust the player not to shoot important NPCs, or they wanted the player to be alone and isolated all the time, for the sake of the horror atmosphere, but needed other living characters to be part of their story. I'm especially annoyed with how often the game puts you on the other side of some barrier when interacting with other living NPCs.

Predictably, things go wrong and you get trapped on board the Ishimura, thus cuing the rest of the game where you have to explore the ship, get its various systems working, kill a bunch of aliens, and find a way off without getting yourself killed. Once on board, you find the bloody remains of crew members and discover audio logs suggesting some type of alien incursion, and before long you're being attacked by the reanimated corpses of the crew, now sprouting alien appendages. Dead Space begins as many horror games do, with a slow and gradual introduction that aims to lay the atmosphere on as thick as possible before the threat becomes apparent and the monsters start coming out in droves to murder you. Playing as a spaceship engineer by the name of Isaac Clarke, you arrive with a small crew on board the USG Ishimura, a colossal 'planet-cracker' mining vessel orbiting a remote planet that sent out a distress signal before cutting all radio contact, with the ostensible goal of figuring out what went wrong and repairing the Ishimura.
