''Alien: Isolation'' is an action-adventure video game developed by the Creative Assembly and based on the ''Alien'' science fiction horror film series. It was published by Sega and originally released for Microsoft Windows, PlayStation 3, PlayStation 4, Xbox 360 and Xbox One on 7 October 2014. The game is set 15 years after the events of Ridley Scott's 1979 ''Alien'' film and follows Amanda Ripley, daughter of ''Alien'' protagonist Ellen Ripley, and her efforts to investigate the disappearance of her mother. Unlike previous video game adaptations of the ''Alien'' franchise, ''Alien: Isolation'' places a strong emphasis on stealth and survival horror gameplay, requiring the player to avoid and outsmart a single alien creature over the course of the game. It was designed more in line with Scott's film as opposed to James Cameron's more action-oriented 1986 sequel ''Aliens'', and features a similar lo-fi, 70s vision of what the future would look like. The game runs on an entirely new engine that was built from scratch to accommodate technical aspects like the game's atmospheric and lighting effects as well as the alien's behavioural design. Upon release, ''Alien: Isolation'' received generally positive reviews from video game journalists and sold over two million copies in Europe and the US as of May 2015. Critics praised the game's retro-futuristic art direction and sound design, but criticized its story, characters, and voice acting. The game won several year-end awards, including Best Audio at the 2015 Game Developers Choice Awards and Audio Achievement at the 2015 British Academy of Film and Television Arts Awards. ==Gameplay== ''Alien: Isolation'' is a single-player action-adventure game with stealth and survival horror features, in which the player controls the protagonist, Amanda Ripley, from a first-person perspective to interact with the environment.〔〔 To advance through the game, the player must explore a space station and complete numerous objectives while avoiding, outsmarting and defeating enemies like human occupants or hostile androids.〔 Objectives range from activating computers to collecting certain items or reaching a specific area in the game. The player has the ability to run, climb ladders, and sneak into vents. The player can also crouch and hide behind objects to break the line of sight with enemies, and covertly peek over or lean around to gain view.〔 The player has also the ability to go under nearby tables or inside lockers to hide from enemies.〔 Unlike previous video game adaptations of the ''Alien'' franchise, ''Alien: Isolation'' features a single alien creature that pursues the player over the course of the game. The alien creature cannot be defeated, requiring the player to use stealth tactics in order to survive.〔 Instead of following a predetermined path, the alien has the ability to actively investigate disturbances and hunt the player by sight or sound.〔 Along the way, the player can use both a flashlight and a motion tracker to detect the alien's movements. However, using any of these increases the chance of the alien finding the player. For example, if the alien is moving and close enough, the tracker's sound will attract the alien, forcing the player to wisely use the tracker and remove it as soon as it detects motion.〔 The motion tracker cannot detect enemies when they are not moving and cannot determine whether the alien creature is up in the ducts or on the ground level.〔〔 Although the player can use certain weapons to defeat enemies, ''Alien: Isolation'' emphasizes evasion over direct combat by providing the player with limited ammunition.〔 The game features four weapons that become available as the player progresses throughout the game: a revolver, a shotgun, a bolt gun, and a flamethrower.〔 The player can also craft several items by collecting schematics and different kind of materials throughout the game. Items range from EMP mines to noisemakers, molotov cocktails and pipe bombs, among others. These items help the player deal with enemies and the alien.〔 For example, the noisemaker can be used to attract enemies in one particular direction. The alien is afraid of fire, so using the flamethrower or a molotov cocktail will make it retreat into the station's ventilation system. The player has a limited amount of health which decreases when attacked by enemies. Nevertheless, the player can increase Amanda's health using medkits, which can be crafted with materials in inventory.〔 The space station is divided into multiple sections connected by trams and elevators. Each section is composed of a set of rooms and corridors separated by doors. Some doors require certain actions to be performed first before entry is allowed. For example, some doors require a keycard or a numbered entry code, while others need to be cut with a plasma torch or hacked using an electronic device.〔 The player may also encounter computer terminals that can be used to access information or trigger in-game actions like disabling security cameras or manipulating the space station's air-purification mechanism.〔 The game features an automap to help players navigate the different areas of the game.〔 To save their progress, players need to locate a terminal in the game and manually insert Amanda's access card in it. If Amanda dies, the player will need to start the game again from the last saved point.〔 In addition to the campaign mode, ''Alien: Isolation'' features a separate game mode, called Survivor Mode, that focuses on short, player-versus-alien scenarios. In each scenario, the player needs to complete a set of objectives while avoiding the alien under a time limit.〔 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「Alien: Isolation」の詳細全文を読む スポンサード リンク
