Dead Space 2 is a survival horror third-person shooter. The player controls Isaac Clarke from a third-person point of view, looking over the character’s right shoulder. The game features no HUD elements, relying on holograms projected from the player character and his weapons to show information such as messages and ammunition count, respectively. Player health and stasis is shown by a visual indicators located on Isaac’s back. Isaac must fight an alien organism that infects and takes control of human corpses, turning them into “Necromorphs”, mutating their bodies.
Necromorphs must be dismembered as the alien organism controls host bodies via tentacles extending into their limbs. Other, larger types of Necromorphs that cannot be dismembered will often have yellow, glowing pustules, indicating weak spots. Occasionally, when an enemy gets close enough to Isaac, they will grab a hold of him, and the player must repeatedly press a key to fend off the enemy, with failure to do so leading to death of the player character.
At these settings, the game is playable, dropping a few times under the 30 fps sweet spot.
