Portal 2

I-Portal 2, eyakhutshwa ngo-April 2011, yinto enkulu emkhakheni wezimidlalo yevidiyo, eyenziwe futhi yanyatheliswa yi-Valve Corporation. Njengomdlalo olandelayo ku-Portal ka-2007 odume kakhulu, yandisa imiqondo yokuqala, egxile kwi-physics, ukwenza umuzwa ocebile, ohanjiswa yindaba. Ngenkathi umdlalo wokuqala wawubhekwa njengesivivinyo esicwengisiwe esifakwe ku-"The Orange Box," i-Portal 2 yaba yimpumelelo enkulu eyathola udumo olubanzi ngenxa yokubhala kwayo, ukudlala ngezwi, izindlela zokudlala ezintsha, kanye nomklamo ophilayo. Itholakala kumapulatifomu afaka i-Microsoft Windows, macOS, Linux, i-PlayStation 3, i-Xbox 360, futhi kamuva i-Nintendo Switch, igame yaqinisa idumela le-Valve ngokuhlanganisa ukuxoxa ngezindaba nomklamo wokudlala oshukumayo. Indaba ye-Portal 2 iqala isikhathi esingachazwanga ngemuva kweziganeko zomdlalo wokuqala. Isihlabani esiyinhloko, u-Chell, owayeseke wabhubisa ubuhlakani bokuzenzela obubi obuyi-GLaDOS (Genetic Lifeform and Disk Operating System), uvuswa ekuboleni emjondolo efana negumbi elincishisiwe esikhungweni se-Aperture Science Enrichment Center. Uholwa yi-Wheatley, ikakhulukazi imbangela yobuntu enomklamo wokuhlakanipha "okuyingqayizivele," edlalwa ngenkuthalo enesikhathi esihlekisayo nguStephen Merchant. Ekuzameni kwabo ukubaleka esikhungweni esonakalisiwe, basivula ngephutha i-GLaDOS, edlalwa futhi ngu-Ellen McLain, ophezulu futhi osabisayo. I-GLaDOS iphinde iqale ukulawula kwayo esikhungweni, ihlukanise u-Chell no-Wheatley, futhi iqale umjikelezo omusha wokuhlola ngenkathi yakha kabusha izindawo zokucwaninga eziwonakele. Isiqendu siyaziswa ngobunzulu nobuhlakani bezakhiwo. Njengoba indaba iqhubeka, kunomzabalazo wamandla ophumela ekutheni u-Wheatley afake umzimba we-GLaDOS bese elawula isikhungo. Uphuma esihlwathini "sokuhlola" kanye nokuhamba okungazelelwe kwamandla aphelele, u-Wheatley uba umphikisi oyinhloko, ngenkathi i-GLaDOS ihlehliselwa esifundweni esingenamandla ebhethri likatamatisi. Lesi siphambaniso siphoqa ubambiswano olungajwayelekile phakathi kuka-Chell no-GLaDOS. Bobabili bayagxunyekelwa emgodini wesikhungo, lapho bahamba khona eziqongweni zokuhlola ze-"old Aperture" ezivalelekile kusukela ngawo-1950, 60, kanye 70. Lapha, umdlali waziswa ku-Cave Johnson, umsunguli we-Aperture Science ongajabuli futhi okhangayo, odlala ngu-J.K. Simmons. Ngemiyalezo eqoshiwe, umlando kaJohnson ubonisa ukuwa okudabukisayo kwenkampani kanye nokuhlangana komuntu we-GLaDOS kumuntu wakhe, uCaroline, okwengeza ungqimba oluthile oluzwakalayo emlandweni womphikisi. Ngokombono wokudlala, i-Portal 2 igcina umakhenikha oyinhloko we-"Aperture Science Handheld Portal Device," ovumela abadlali ukuthi benze izimbobo ezimbili ezixhunywe ezindaweni ezithambile ukuze bahambe phakathi kwesikhala ngokushesha. Kodwa-ke, umdlalo olandelayo wethula iqoqo lezinto ezintsha zokuhlola ezenza izinselelo zibe nzima futhi zihlukahlukene. "Ama-Hard Light Bridges" anikeza imigwaqo eqinile; "Ama-Thermal Discouragement Beams" ayizibhamu ezingadluliselwa ukuze zichithe izibhamu noma zivule izishintshi; futhi "Ama-Excursion Funnels" enza njengezibhamu zokuhambisa umdlali noma izinto. Mhlawumbe isengezo esibaluleke kakhulu ukwethulwa kwamajeli okuhambisa, iziqukathi zesikhathi sakudala se-"Aperture". I-"Repulsion Gel" eluhlaza okwesibhakabhaka ivumela abadlali ukuthi babaleke bafeze ukuphakama okukhulu, i-"Propulsion Gel" eluhlaza okwesibhakabhaka inikeza isivinini esiphakeme, futhi i-"Conversion Gel" emhlophe ivumela izimbobo ukuthi zibekwe ezindaweni ezingazange zisebenze ngaphambili. Lezi zinto zisebenza nenjini ye-physics ngezindlela ezihlukahlukene, zidinga abadlali ukuthi bahlanganise amandla nokuhambisa imvelo ukuxazulula amakamelo okuhlola. Ngaphezu komkhankaso womdlali oyedwa, i-Portal 2 ifaka imodi yokubambisana enamandla enezindaba zayo ezihlukile. Abadlali ababili balawula amarobhothi i-Atlas ne-P-Body, ezakhiwe yi-GLaDOS ukuze baqhubeke nokuhlola ngemuva kokuthi izibonelo zabantu zithathwe njengeziyinkinga kakhulu. Le modi idinga izinga eliphakeme lokudidiyela, njengoba abadlali kufanele basebenzise izimbobo ezine futhi basebenze ndawonye ukuze bahambe ngezithiyo. Umkhankaso wokubambisana ugxile ekuthembekeni nasezingxoxweni, uvame ukuphoqa abadlali ukuthi bahlele izenzo zabo ngokuphelele noma badlulise izinto phakathi komoya. Indaba yomodi yokubambisana yandisa ulwazi, ekugcineni ihambise amarobhothi ukuba athole indawo yokulondoloza eyimfihlo yabantu abahloliwe, isambulo esibuyela emuva endabeni yomdlali oyedwa. Ukwakhiwa kwe-Portal 2 kwakuyisenzo esikhulu esahlehlela kusukela embonisweni wokuqala obizwa nge-"F-STOP"—ongazange ube nezimbobo—ebuyela kumakhenikha ayinhloko ayithandayo abalandeli. Ithimba lokubhala, elifaka u-Erik Wolpaw, u-Jay Pinkerton, no-Chet Faliszek, lakha isikripthi esinobunzima ngobuhle obumnyama kanye nencazelo yengqondo. Isipiliyoni sezwi somdlalo sibaluleke ngokufanayo, sibonisa ingoma ephumelelayo ka-Mike Morasky ehambisana ngezindlela eziguquguqukayo nezinto abadlali abazenzayo. Isibonelo, ukusebenzisana nezinto ezithile zokuhlola kwengeza ungqimba kumculo. Umdlalo ubuye ubonise izingoma zoqobo ezivela ku-The National kanye nengoma yokugcina yesikweletu, "Want You Gone," ka-Jonathan Coulton, kulandela isiko lomdlalo wokuqala, "Still Alive." Lapho ikhutshwa, i-Portal 2 yathola impumelelo enkulu yezimpendulo, yafinyelela isikolo esingu-95/100 ku-Metacritic. Yazuza imiklomelo eminingi, kufaka phakathi i-"Ultimate Game of the Year" kuma-Golden Joystick Awards kanye nemiklomelo ephezulu yendaba yayo nokudlala kwayo kuma-Game Developers Choice Awards. Abagxeka badumisa umdlalo ngokukwazi kwakhe ukufundisa abadlali ngamakhenikha ayinkimbinkimbi ngaphandle kwezinkulumo eziningi futhi ngesigqi sawo esingenamaphutha. Ifa layo liyaqhubeka ngokusebenzisa umphakathi ophilayo we-modding, osekhelwa yi-"Perpetual Testing Initiative" ye-Valve, eyavumela abadlali ukuthi benze kalula futhi bahlanganyele izahlulelo zabo. Namuhla, i-Portal 2 ihlala iyisilinganiso sama-puzzle-platformers futhi ibhekwa kabanzi njengomunye wemidlalo eminingi yevidiyo enkulu kunazo zonke, isebenza njengesikole samakhosi sendlela yokuhlanganisa umdlalo nendaba ngokuziphatha okungenamahloni, okunamandla.
