“創新概念下的續作【傳送門2】,跟一代比起來,二代絕對更加的精緻,遊戲長度也差不多是一代的五倍以上,而且除了單人模式以外還新增了多人模式以及關卡編輯,讓玩家能夠一同與朋友解謎或自創關卡。單人模式在劇情的多元化下,讓你不但不會厭倦解謎的過程,反而還會繼續吸引你前進下去,不論是遊戲劇情設定上,連音樂也是本作精華之一。相信【傳送門2】的故事絕對能深深吸引到你。by.A.K”

About This Game

Portal 2 draws from the award-winning formula of innovative gameplay, story, and music that earned the original Portal over 70 industry accolades and created a cult following.

The single-player portion of Portal 2 introduces a cast of dynamic new characters, a host of fresh puzzle elements, and a much larger set of devious test chambers. Players will explore never-before-seen areas of the Aperture Science Labs and be reunited with GLaDOS, the occasionally murderous computer companion who guided them through the original game.

The game’s two-player cooperative mode features its own entirely separate campaign with a unique story, test chambers, and two new player characters. This new mode forces players to reconsider everything they thought they knew about portals. Success will require them to not just act cooperatively, but to think cooperatively.

  • Complete two-person co-op: Multiplayer game featuring its own dedicated story, characters, and gameplay.
