模擬山羊

游戏玩法

《模拟山羊》是一款开放的第三人称视角游戏，而玩家所控制的主角是一只山羊。 玩家能够自由探索游戏世界，并进行跳跃、奔跑、撞击、舔物品等互动。 舔物品会使山羊的舌头吸附在物品上，能让玩家把物品拖来拖去，直到他们松开为止。在任何时候，玩家都可以让山羊进入布娃娃模式，允许游戏的物理系统来接管控制；而另一个操作能让游戏以慢动作运行。游戏中有许多环境物件能让玩家操控山羊做出特技动作，例如用弹跳床或大风扇把山羊弹射到空中。模拟山羊有个类似托尼·霍克系列等滑雪游戏的记分系统，玩家能完成特技或一些动作来获得分数，若玩家将特技组合成组合技，则会获得分数加成，当组合技完成时，会直接将获得的分数加倍。游戏中会给玩家一些游戏目标，比如达到某个高度、摧毁某些物件或完成翻滚动作，不过玩家不需要完全遵照这些指示游戏。
游戏世界中藏有一些小的金色山羊雕像。收集到这些雕像并重启游戏后，山羊就能在游戏中使用一些装备，或者是将山羊改造，例如把山羊变成恶魔山羊、长颈鹿或鸵鸟，或是给山羊装上喷射背包等等。游戏中也有许多彩蛋分布在游戏中，比如能成为山羊女王的城堡，或是某个能获得类似索尼克旋转攻击的地方。模拟山羊的研发组长Armin Ibrisagic在游戏释出后表示，模拟山羊以戏谑性的方式模仿了炼狱，并以此作为游戏背景，也留下了一些与天堂和地狱相关的东西，而之后也被许多玩家在游戏中发现。此外，Ibrisagic还提到了游戏中，有以2014年乌克兰革命为基础的物件，然而在游戏中其实就是一小群抗议群众举著荒谬和猥亵的标语。

开发

当时刚完成新游戏《Sanctum 2》的Coffee Stain Studios，在2014年1月举办了为期一个月的内部Game jam活动，而《模拟山羊》一作原先只是在活动中展示的一个搞笑原型。研发组长Armin Ibrisagic形容模拟山羊是：“一个老派的滑冰游戏，不过这次你并不是变成一个滑冰选手要表演特技，而是变成一个破坏东西的山羊 。”模仿《QWOP》用多个按键控制山羊的版本，后来被《托尼·霍克职业滑板》风格的设计所取代，并成为定案公开展示。Ibrisagic开玩笑似的尝试让同事相信山羊会像猫一样，在网络上取得大量关注，并开始专注在山羊的项目上。

 The prototype used Nvidia PhysX and an Apex physics engine with ragdoll physics for the goat and human models within the Unreal Engine 3, a game engine they were familiar with from the Sanctum series. In-game assets were purchased from third-party vendors instead of developed in-house, such as the original goat model which the studio acquired for use for less than $20. The prototype was meant to be a parody of various other "weirdly successful" Simulation games presently available, such as Euro Truck Simulator. Ibrisagic had no intention of this becoming a full title, instead only offering the prototype for him and other developers to learn the Unreal Engine alongside other developers that were developing prototypes in more earnest.
游戏开发到alpha阶段时，它的画面就已经被做成影片，并由Coffee Stain Studios上传到YouTube，在两天内便获得巨大回响。 许多支持者也因为游戏原型的众多错误，希望他们开发一个完整的正式版本。 The appeal of the video was also picked up by the agricultural magazine Modern Farmer. Some journalists suggested that the title be developed into a full game even knowing it was meant as a joking title; GameSpot editor Danny O'Dwyer supported the full release of the game arguing that "games should be dumb once in a while".
The large positive response to the alpha footage convinced the studio to develop Goat Simulator as a full title to Steam, putting more people on the title. The team, having no plans for a full release, debated on whether to approach a large publisher to receive funding to help make the title into something like Grand Theft Auto, but decided to stay with a small, inexpensive title that would be truer to the teaser video. Recognizing that the glitching was part of the game's appeal, Ibrisagic only sought to fix software bugs that might cause the game to crash, leaving in the other glitches and bugs associated with the physics engine as the results from these were "really hilarious". They limited themselves to a short development time of four weeks without significant management oversight as to set an urgent but realistic goal to bring the game to a playable state. Ibrisagic felt it was important for the game to be supported on Steam, but initially feared that Valve Corporation would not accept the quirky title. He instead found Valve to be welcoming of the title, including a joking response from the company that stated "[Valve's marketing manager DJ Powers] has started wearing a goat costume to work he’s so excited about this game". As part of its release, Coffee Stain added support for Steam Workshop which would let players modify the game, aware that players would likely create levels and scenarios that will glitch and crash the game for humorous results. While the physics engine allows for spectacular rendering of destruction of the game environment, which is a main feature of the game, Coffee Stain acknowledged the downside of this as "it would synchronise terribly in multiplayer". They estimated that adding multiplayer would remove "90 percent of the physics" and many other features, and left the game as a single player title at launch. The studio considered that it only spent a couple months to complete the Windows version, and opted to outsource versions for OS X and Linux, with Ryan Gordon handling the porting.

释出及推广

Coffee Stain Studios released Goat Simulator worldwide on 1 April 2014, aware that tying the date with April Fools' Day may raise doubts on the validity of the game. Those that pre-ordered the game through Coffee Stain's website received early access to the title three days ahead of release. The official release trailer for Goat Simulator is a loose parody of the highly praised teaser trailer released for Dead Island, showing, among shots of the game, reversed slow-motion footage of the goat crashing through a building after being launched from an exploding gas station.
The studio released a free expansion and patch to the game on 3 June 2014, which in addition to fixing game-breaking issues, added new goat models, a new map to explore based on a seaside town with a carnival, more game-breaking issues, and local multiplayer for up to 4 players via split-screen. Ibrisagic believes that adding multiplayer support atop Steam Workshop support will allow creative users to develop new gameplay modes that will extend the title's playability. The patch also adds in additional controls that the player can use to make the goat perform various freestyle tricks comparable to those in Tony Hawk's Pro Skater. The studio released a second free patch to the game on 20 November 2014 including elements that parody massive multiplayer online games like World of Warcraft, though remains a single player or local multiplayer experience.
A paid-content expansion titled "GoatZ" was released on 7 May 2015 as downloadable content for the game on personal computers and a stand-alone application for mobile devices. It was developed by Coffee Stain's partner studio Gone North Games. The expansion's content spoofs zombie-based survival games, such as DayZ, and includes a new map and gameplay aspects such as fighting off zombies and crafting. The title itself plays off DayZ as well as a play on the Internet meme goatse.cx. In a cross-promotional "GoatBread" update with Bossa Studios' I am Bread to be offered in late 2015, a free update to Goat Simulator will allow the players to select a piece of bread as their avatar, while I am Bread will add in a "RAMpage" mode based on Goat Simulator. Another add-on, the "Super Secret DLC" package part of a cross-promotion with Overkill Software's Payday 2; the Payday-inspired content for Goat Simulator included additional playable characters including a camel, flamingo, and a dolphin in a wheelchair, while Goat Simulator content will be added to Payday 2. These were released in January 2016. Goat Simulator decorative content was added to Rocket League in a mid-2016 update. Another expansion, "Waste of Space", was again developed by Gone North Games and released on 26 May 2016. The expansion features a new map based on a space colony, and spoofs much of the recent science fiction media genre.
The OS X and Linux ports were released on 27 June 2014. Following the game's digital release, Koch Media agreed to distribute the game in UK and EU retail stores starting in May 2014.  Similarly, Deep Silver approached Coffee Stain Studios to work out a deal to publish the title in North American retail markets starting in July 2014. At Microsoft's presentation at the 2014 Gamescom convention in August, Goat Simulator was announced as one of several titles to be coming to the Xbox One platform with the help of Double Eleven studios, and later confirmed to be also arriving for the Xbox 360, with both versions released on 17 April 2015. Koch Media also distributed a retail version of the Xbox One version, including all additional downloadable content, across Europe for release on 4 March 2016. Coffee Stain Studios also released ports for iOS and Android in September 2014. PlayStation 3 and PlayStation 4 versions, also ported by Double Eleven, were released on 11 August 2015.
With the acquisition of Coffee Stain through THQ Nordic on 14 November 2018, it was announced that a Nintendo Switch version of Goat Simulator would be released. Goat Simulator: The GOATY, which includes all expansions to date, was released on 23 January 2019.
