In space, no-one can hear you scream... As trite and cliched as that sentence is, it does much to capture the spirit of Alien: Isolation, a game that is designed from the ground up to scare the player out of their wits.
Set 15 years after the events depicted in the film Alien, Alien: Isolation places the player in the role of Amanda Ripley, Ellen Ripley's daughter; Ellen being the lead character in the Alien franchise.
Amanda is searching for the flight recorder of the Nostromo, the ship that her mother was on before she destroyed it at the end of Alien. As part of her search she has been working from space station Sevastopol, which as the game begins becomes infested by a xenomorph.
Amanda is not a gun-toting marine, so is not armed with the now-familiar M41a pulse rifle but instead has in her arsenal a motion tracker, flash light and her wits. There is only one alien in Alien: Isolation and Amanda has no means to attack it directly. The only means of defence she has against the being is either to hide from it or do her utmost to evade it by moving stealthily.
The emphasis of Alien: Isolation is very squarely on suspense and fear, something that will make this a good fit for fans of the first Alien film.
