Dead Space

The first game in the series, released for the PC, PlayStation 3, and Xbox 360. Engineer Isaac Clarke is part of a team responding to a distress signal from the USG Ishimura, a giant ship designed to "crack" planets for resources. When the Ishimura crew doesn't receive their ship, Isaac's team is forced to crash land inside and, after leaving their damaged shuttle, the crew finds the Ishimura in severe disrepair and swarming with Necromorphs. When Isaac then ends up separated, the team splits up to co-ordinate repairing several ship areas and reunite to escape. Isaac also has a personal stake in fixing the Ishimura; his entire reason for volunteering was to visit his girlfriend, Nicole Brennan, who is also trapped aboard.
