誰也沒有想到，自2007~2008年推出的橘盒附贈的第一代《傳送門》，結合益智與射擊移動的理念在一推出後廣受玩家群好評，這也使得《傳送門》成為活栓公司近年來評價最好的遊戲之一。如今，這款經典作品將以全新的姿態再度帶給大家比前作更多的謎題，更多的樂趣。
當然，這麼一款如此用心的益智射擊遊戲，IGN給分自然就不會吝嗇。以下是評測結果：
＂The original Portal benefitted from its brevity. It had a concise story paired with inventive first-person puzzle mechanics that challenged you to be creative while pulling the trigger. Portal 2 makes the original look like the prototype it was. It's filled with a larger cast of characters vividly brought to life through brilliant writing and some of the best voice acting in video games. Its puzzles are challenging without being unreasonable, and, once you're finished with the single-player mode, one of the best co-operative experiences on the market awaits. Valve cuts no corners and finds ways to make you care about everything from the major characters to the cubes used to solve puzzles. From the beginning of the single-player story to the end of the co-op mode, Portal 2 is a novel, unforgettable experience.＂
《傳送門》的魅力在於它的簡潔。它有一個簡潔的故事，搭配創新的第一人稱解謎的挑戰，並給予你按下板機發揮創意的機會。相比之下《傳送門2》使得原來的《傳送門》就像它的原型。大量且寫實的角色演出搭配好的劇本演出和配音。謎題具有相當的挑戰性也非常的合乎常理，而且，一旦你完成了單人遊戲模式中，還有更棒的多人合作模式等著你挑戰。活栓製作團隊去蕪存菁的設計能讓你能專注在角色互動以及解謎上，從單人模式到多人合作，《傳送門2》將帶給你有如小說般精彩且難忘的遊戲體驗。
《傳送門2》
Presentation：9.5Great writing, an entertaining story and plenty of surprising developments. Portal 2 never fails to entertain.
傑出、富娛樂性的劇本且具有深度的設計，《傳送門2》從頭到尾絕無冷場。
Graphics：9.0
This isn't the flashiest game you'll play, but the imaginative art style, stage designs and animations more than make up for it.
儘管這不是你玩過最亮眼的遊戲畫面，富有想像力的美術風格、關卡設計以及動作設計將會讓你為之一亮。
Sound：10
Stephen Merchant as Wheatley steals the show while Ellen McLain as GLaDOS and J.K. Simmons (Spider-Man, Juno) turn in solid performances. Impressive soundtrack too.
Stephen Merchant 和 Wheatley的表現比Ellen McLain扮演的GLaDOS以及J.K. Simmons還要棒（XD），原聲帶也是令人驚艷。
Gameplay：9.5
The puzzles start small and continue to ramp up through the co-op. The challenges are never chores and are always satisfying to solve.
從簡單的謎題到棘手的多人合作，《傳送門2》帶給你源源不絕且絕不無聊的遊戲體驗，並且會讓你樂意去面對他。
Lasting Appeal：7.5
Though play time will vary, expect the single-player and co-op to take roughly 10 – 12 hours. Afterward, unless you want to relive the story, there isn't a huge incentive to replay.
雖然遊戲帶給玩家從單人到多人合作總共長達10-12小時的驚人體驗，但之後除非你想再回味故事，不推薦重破。
總分：9.5(Amazing)
