往日不再
是一款由索尼本德工作室開發的生存恐怖遊戲，索尼互動娛樂於2019年4月26日在PlayStation 4平台發行，並於2021年5月18日在Microsoft Windows平台上發售，成為繼《地平線 黎明時分》後第二款SIE全球工作室的自家旗下工作室脫離平台獨佔登陸PC的遊戲作品。遊戲背景設定在一場嚴重疫情爆發兩年後的末世奧勒岡州。曾為法外之徒的浪跡者迪肯·聖約翰發現他被認為已故的妻子莎拉可能還活著，於是出發尋找她。透過《往日不再》第三人稱遊戲視角，玩家可在開放世界裡到處探索。玩家可使用一般武器、近戰武器與簡易武器，並可藉由潛行技能抵禦來者不善的人類與被稱為“異變者”的食人生物。遊戲其中一個主要機制為迪肯的機車，作為玩家主要的交通運輸工具及可移動置物空間。
《往日不再》為本德工作室的第一個開放世界專案、繼《》（1999）之後第一部原創作品，以及開發十多年的掌上主機外傳遊戲後第一個專為家用主機開發的遊戲。本作開發耗時約六年，本德工作室為此擴大至近三倍人力。《往日不再》主要受《末日之戰》、《陰屍路》及《飆風不歸路》啟發。本作於2016年E3電子娛樂展正式亮相，原定2018年正式發行卻被數次推遲。
本作發行後收到混和評價：故事劇情、任務設計與技術問題遭到批評，遊戲畫面、角色AI與山繆·維特威扮演迪肯的表現則得到稱讚。本作常被認為是索尼在PS4世代裡所開發過較差勁的本家遊戲之一。儘管未大受好評，《往日不再》依舊取得了商業成功；本作銷量超越本德工作室以往開發所有遊戲的總和，並成為美國2019年第19名最賣座遊戲。2021年，據傳本作開發團隊曾向索尼提議發展續作，但並不成功。
《往日不再》是款第三人称的生存恐怖动作冒险游戏。玩家將扮演賞金獵人迪肯·聖約翰（Deacon St. John），透過行走或騎乘「浪跡者機車」探索世界，在遊玩過程中，玩家除了要對抗倖存的人類掠奪者，還要面對因瘟疫危機產生的喪屍與受感染的動物威脅。遊戲原本擁有「簡單」、「普通」、「困難」3種難度，6月追加更新了難度更高的「生存」模式，一些如快速移動和求生視野的特殊能力都無法使用。
遊戲背景為發生全球瘟疫危機兩年後的「俄勒冈州」，遊戲世界包含了森林、河流、山脈與雪地等各種環境，而遊戲內的動態天氣變化系統會對地圖造成影響，例如下雪時，玩家的能見度除了會降低，騎乘機車時也會比較容易打滑。遊戲中共有六個地區，這些地圖會隨著玩家的故事進度逐漸解鎖。每個地區都有「營地」，且各自擁有獨特的道具。
喪屍會進食與遷徙，喜歡潮濕陰冷的環境。玩家在遊戲中最常遇到的是「暴走者」，他們通常群聚再一起行動，其他包括會在玩家衰弱時攻擊的「幼變者」、發出聲音吸引喪屍的「尖嘯者」和體型巨大的「殘暴者」。地圖上佈滿著感染區，每個感染區的在地圖上顯示的紅點代表著異變者巢穴，玩家可透過燃燒彈、遙控炸彈以及射擊燃料箱來清理，每清理一個感染區，玩家將解鎖快速傳送至該區域安全屋、大量獎勵還有營地的信任值。
遊戲提供不少戰鬥方式，包含了各種槍械、近戰武器及火藥，而不同的武器選會出現不同的打擊效果，也可以在敵方未察覺時繞背完成暗殺，遇到大量敵人時，可以投擲汽油彈或朝著汽油桶開槍造成爆炸來攻擊敵人。本作的技能樹共分為遠程、近戰以及求生三種。
機車是玩家在遊戲中的重要工具，玩家可以騎乘機車上山下海也能撞開成群結隊的喪屍，一旦燃料耗盡或零件受損，玩家必須徒步去附近的營地購買燃料、零件或推車前進，也可以冒著引發警報器的風險拆除路邊車輛的零件。機車也是本作的存檔點之一，只要玩家死亡，就會在機車附近復活。玩家不只可以搶奪他人的機車，也能透過升級強化它的行駛速度與武器裝備容量。
「信任值」是本作的重要設定，玩家的信任值越高越有機會獲得強力的道具，數值夠高的話可以開啟支線任務，但營地的信任值是分開計算的。遊戲還設有「拍照模式」，除了基本的角色表情和18种滤镜效果，還能進入进阶模式，對照片的55项设定进行处理。
一種病毒席捲全球，使絕大部分人類變成稱為“異變者”的殘暴喪屍。在不久將來的奧勒岡州，法外之徒迪肯·聖約翰（山繆·維特威）和威廉·“酒鬼”·格雷（）以及迪肯妻子莎拉·艾琳·惠特克（），試圖逃出生天。他們找到一架只剩兩人空間的NERO直升機。莎拉搭上直升機，迪肯則因酒鬼受傷選擇留下來幫助他，並向妻子保證會再與她團聚。
兩年後，迪肯與酒鬼在太平洋西北地區擔任傭兵。莎拉被認為已亡故，因為她據信曾待過的NERO難民營遭到異變者入侵而淪陷了。兩人計畫前往北方追尋更好的生活，但他們遭到一群邪教徒“安息者”攻擊。酒鬼的右手臂在這次攻擊中被嚴重燒傷，迪肯到處尋找醫療用品來幫他治療。後來，兩人得知安息者正在懸賞他們的人頭。迪肯看到一架NERO直升機並跟著它，並見到兩年前帶莎拉撤離的研究員詹姆斯·歐布萊恩（貝爾納多·德·寶拉）。歐布萊恩透漏莎拉搭的直升機中途轉向了另一個營地，代表她可能還活著。
酒鬼的健康狀況持續惡化，於是迪肯帶他去由“鐵漢”·麥克·威爾卡克斯（埃里克·阿蘭·克萊默）及雷蒙·“狂徒”·薩爾柯奇（）掌管的洛斯特湖營地。營地的醫生將酒鬼腐壞的手臂截肢以挽救生命，歐布萊恩則答應只要迪肯願意支援NERO正在進行的研究計劃就協助他找莎拉。與此同時，狂徒對安息者與洛斯特湖間脆弱的結盟不以為然；他私自做了交易將迪肯出賣給安息者。迪肯發現安息者首領“卡洛斯”其實是傑西·威廉森（），一名以前在摩托幫的日子裡結下樑子的敵人。迪肯逃出安息者的營地並炸掉上游的水壩，淹死傑西與其餘教徒。
迪肯得知莎拉身為擁有聯邦安全權限的政府研究員，在營地撤離中應有優先資格，歐布萊恩則證實她被轉移到位於火山口湖的一座軍事前哨站，如今已被德舒特縣民兵團佔據。他還警告迪肯異變者正在進化，變得越來越危險。迪肯贏得民兵首領馬修·蓋瑞特上校（）的入伍許可並與莎拉重聚，此時她正在研發用來對付異變者的生化武器。迪肯和莎拉決定前往她的舊實驗室找一台DNA合成儀，他們在那知曉她的研究曾被用來研發異變者病毒。
在實驗室裡，莎拉表示她正致力於治癒異變者而非消滅他們。迪肯建議他們應在她的新實驗室裡尋找治癒解方，愈發偏執的蓋瑞特卻將莎拉實施保護管束。迪肯企圖救她但失敗並被狂徒逮捕。一名富有同情心的軍官戴瑞克·庫里（）放走迪肯，於是迪肯回到洛斯特湖，此時那裡已遭到民兵團攻擊。迪肯聯合洛斯特湖營地剩餘成員及其他營地的人對民兵團展開報復行動，以一台炸彈卡車進攻他們的總部。迪肯殺死狂徒，莎拉毒死蓋瑞特，民兵團於是被瓦解。
迪肯、莎拉、酒鬼和他們的朋友們定居在洛斯特湖。歐布萊恩聯絡迪肯並揭曉NERO一直以來都知道異變者病毒具有突變效果，而他自己就是一名突變異變者。他警告迪肯NERO正在前來路上且任何辦法都不能阻止他們。
《往日不再》的開發商本德工作室為索尼的其中一家遊戲開發商。本作的核心開發團隊包含工作室導演克里斯多福·里斯（Christopher Reese）、遊戲總監傑夫·羅斯（Jeff Ross）及創意總監約翰·加文（John Garvin），他們早在1990年代本德工作室在開發《》時就是工作室的一員。《往日不再》是該公司第一款開放世界遊戲、繼《》（1999）之後第一個原創智慧財產，以及在《》（2007）之後第一部在家用主機上發行的遊戲。
《往日不再》的完全開發肇始於2015年，而本作的開發週期持續了六年。開發團隊受到《末日之戰》、《陰屍路》及《飆風不歸路》這些遊戲開發初期當紅的影劇作品啟發，同時本德工作室將開發團隊從50人大大擴張到130人。2019年3月10日，遊戲開發完成，本德工作室證實遊戲已進入完成版，代表已可用於量產與發行。
During the game's pre-production, the team decided it would be an open world project. The game is set in Central Oregon, where Bend Studio is located. According to Garvin, Central Oregon has diverse terrain and landscapes ranging from snowy mountains to deserts, making it an ideal setting for a sandbox title. According to lead designer Eric Jensen, the open world mechanics of "Days Gone" were designed by a small team of five or six developers who "had to think smart and efficient with all of our design choices knowing the manpower limitations". The studio initially underestimated the manpower needed to develop the project, thinking a team of 50 people would suffice. While the game is open world, the team omitted a good deal of filler content. Most of the game's missions are scripted and connected to its main story. The team's goal was to replicate the successes of linear games such as the "Uncharted" series in an open world setting.
While the enemies featured in the game are similar to zombies, Bend Studio named them "Freakers." The Swarmers in the game were inspired by "a guy who was doing a YouTube video where he was moving weird," while the Newts were inspired by contortionists. Swarmers may congregate to form a horde of 50 to 500. To better optimize the horde, Swarmers are divided into small clusters. If they are close to the player, some of these horde clusters will split off from the main group, making them easier for players to manage. In a large horde, there are eight Swarmer character models; the team modified the height of each one to make their appearance and behaviors unique. The team spent a lot of time working on the group artificial intelligence (AI) to ensure the horde would not only charge at Deacon in a straight line but would also make use of the terrain to overwhelm the player character.
"Days Gone" has multiple, intertwined stories, which allows players to switch between narratives. The team wanted to keep the narrative interesting and fresh. The game constantly keeps track of player's progress. The team were inspired by Netflix's menu. The game initially allowed Deacon to make decisions that can change the narrative; this feature was removed from the final game because the team had difficulty showing players the impacts of these decisions. According to Garvin, by removing these narrative choices, Deacon's personality would be better reflected because some of these choices may allow him to commit egregious or cruel actions that do not fit his personality.
According to Garvin, the game's main theme is "redemption." The journey would see Deacon, who is often seen as an outsider, grow and evolve into a capable leader. Garvin added that despite the game's post-apocalyptic setting, the team aimed to deliver a more hopeful theme because the story of Deacon concerns the way he can make the world a better place and explores the idea that surviving is not the same as living. The game's story and themes were inspired by "The Road", "The Passage" and "I Am Legend". Because Deacon is a member of a motorcycle club, the team researched the US-based biker gang Hells Angels.
Garvin, who was impressed by his work on "", invited Nathan Whitehead to compose the music for "Days Gone", which was performed by the Nashville Scoring Orchestra and soloists. Whitehead spent two years working on the game's soundtrack. The instrumentation is centered around guitar, which Whitehead said was an "obvious choice" for both the character of Deacon—a bounty hunter and biker—and for the Pacific Northwest setting. Whitehead added that the game's music, which combines "folk Americana and a touch of rock elements," is a good fit for the setting. To accommodate the video game medium's interactivity, the score for "Days Gone" was built up in layers that the game engine could add or remove. As a result, the score dynamically changes in accordance with the gameplay. 遊戲起初計畫2018年發售，後來延後到2019上半年。索尼本德工作室於2018年6月7日公布了遊戲將於2019年2月22日發售，後來又延後到同年4月26日發售。2021年2月，索尼宣布本作将于2021年春季登陆Windows平台。
珍藏版包含了迪肯模型、各項飾品、迷你畫集和原創音樂集以及遊戲道具，玩家預定遊戲的實體版還可以獲得限量造型棒球帽一頂。在日本，遊戲廠商還和服装设计公司迪賽合作推出夾克、牛仔背心、T恤與帽子。 Publisher Sony Interactive Entertainment unveiled "Days Gone" at E3 2016. While the game was originally planned for a 2018 release, it was delayed to the following year. The release was postponed from February 22, 2019, to April 26 in the same year to avoid competing with other triple-A titles such as "" and "Anthem". As part of Sony's efforts to bring more of its first-party content to personal computers following "Horizon Zero Dawn", "Days Gone" released for Windows via Steam and Epic Games Store on May 18, 2021.
Upon release, Bend Studio supported the game with free downloadable content. In June 2019, Survival difficulty mode, which modifies the head-up display and disables options to fast travel, was introduced. This was followed by 12 weekly challenges, in each of which players' performances are classified into Gold, Silver and Bronze rankings. Players receive credits that can be used to purchase new characters and other accessories. In September 2019, Bend added New Game Plus and the MB-150, a sniper rifle from the "Syphon Filter" universe, into the game. Bike tanks, decorations, and frame paint inspired by "Death Stranding" were released in November 2018. 《往日不再》在商業上取得不錯的成績，但媒體方面卻得到褒貶不一的評價，在Metacritic上，遊戲基於108個媒體評論獲得了71/100分。《富比士》的戴夫·蒂尔（Dave Thier）認為遊戲之所以評價和銷量有這麼大的差異是因為「專業偏見（Bias Of Expertise）」。評論員比一般玩家遊玩過更多同樣類型的遊戲，長時間遊玩遊戲讓評論員不經意的比較先前在其他遊戲遇到的類似場景與玩法，使得最後得出的分數遠低於玩家分數。
Destructoid的克里斯·卡特（Chris Carter）喜歡遊戲音樂和技能樹的設計，但即便如此《往日不再》只是略高於平均水準。《Fami通》的編輯們認為遊戲呈現一個充滿緊張、危險的殭屍世界，喪屍的存在、容易折損的武器和機車油量都提醒著玩家這是一個殘酷的生存世界。
GamesRadar+的里昂·赫爾利（Leon Hurley）認為遊戲儘管有著眾多BUG和凌亂的劇情問題，但仍然是個引人入勝的冒險開放殭屍世界。IGN的露西·奧布里恩（Lucy O'Brien）給予遊戲6.5/10分，表示「遊戲在前半段很好的描述迪肯的感情故事以及他行事的動機，但後面劇情就亂了頭緒。遊戲的確有它好玩的部分，但重複的任務設計、平淡無味的劇情和大量強制性的內容，且設定也不夠末日，這個遊戲難以讓人記住。」。
《電子遊戲月刊》編輯喬西·哈蒙（Josh Harmon）直言《往日不再》是索尼第一方中罕見不如預期的作品。Digital Foundry認為索尼本德工作室第一次開發3A遊戲表現合格甚至超出預期，例如光影效果和天氣系統。
《往日不再》在英國取得不錯的銷售成績，發售當週成為實體銷售的冠軍，並連續三週保持冠軍位置。即使《往日不再》是一個全新IP，遊戲在日本首週共售出11萬4319份，並連續兩週獲得銷售第一。同時首週的銷量超過《地平線 黎明時分》和《战神》，只排在《神秘海域4：盗贼末路》與《蜘蛛侠》後面。
On April 9, 2021, Jason Schreier of Bloomberg News revealed Bend Studio had pitched a sequel to "Days Gone" but that the first game's mixed critical reception and lengthy development process caused Sony to reject the proposal. Shortly afterward, Ross confirmed "Days Gone 2" had been pitched to Sony but that many of the details could not be confirmed due to a non-disclosure agreement. He also revealed that part of the plan for the sequel was a "shared universe with co-op play," which was not included in the original "Days Gone" due to staffing constraints.
While appearing on a podcast with David Jaffe, the creator of the "God of War" franchise, Garvin said, "If you love a game, buy it at fucking full price," and implied "Days Gone" did not receive a sequel partly because it did not turn enough profit. Garvin came under fire for his remarks; commenters said "Days Gone" had already benefitted from fan support during its release, and that it was unreasonable to ask someone to spend US$70 on an unknown game. Others noted that Sony ultimately controls sales of PlayStation games and offers free demos, and the onus could not be placed entirely on the purchasers. Following Garvin's comments, Jensen thanked players for their support, no matter when they had purchased or played it.
According to David Jaffe, then chief executive officer of SIE Worldwide Studios, Shawn Layden had vigorously supported "Days Gone". But as soon as Layden left his role in September 2019, Jaffe said ""Days Gone" was dead". Jaffe also said that when trying to pitch a sequel "it was just an uphill battle the whole time" and Ross stated that Sony requested if Sony IPs could be used instead like "Syphon Filter". Ross said the sequel would have explored a more technical direction among detailing other features.
Ross claimed that the game sold over 8 million copies, yet was treated as a "disappointment" by local studio management. This was in response to the official announcement that "Ghost of Tsushima", another SIE first-party game (developed by Sucker Punch Productions), had sold over 8 million copies. The sales numbers provided by Ross were disputed as they were based on a PlayStation Trophy data tracking site. Ross went on to say that whilst at Bend Studio he saw Days Gone officially sell over 5 million copies, the tracking site at the time suggesting 5.8 million copies sold.
