An Android version of the game was released on May 31, 2011 on the Amazon Appstore, while it was also released to the Android Market (now Google Play) on December 14, 2011. On February 16, 2012, a version was released for BlackBerry PlayBook. Later, a BlackBerry smartphone version of the game was released on January 2013 following the launch of BlackBerry 10. Furthermore, both the original Windows and Mac version of the game have been re-released with additional content in a Game of the Year version.
The game received a positive response from critics, and was nominated for multiple Interactive Achievement Awards, alongside receiving praise for its musical score. A sequel, called Plants vs. Zombies 2: It's About Time, was released on August 15, 2013 for iOS.
In Plants vs. Zombies, players place different types of plants and fungi, each with their own unique offensive or defensive capabilities, around a house, in order to stop a horde of zombies from reaching the house of the residents. The playing field is divided into 5-6 horizontal lanes, and with rare exceptions, a zombie will only move towards the player's house along one lane (the main exception is if it has taken a bite out of a garlic). Planting costs "sun", which can be gathered for free (albeit slowly) during daytime levels and by planting certain plants or fungi. Most plants can only attack or defend against zombies in the lane they are planted in. In later levels, players can purchase upgrades with different offensive and defensive abilities.
The game uses several different level types and layouts. The game starts out in a front yard, and progresses to nighttime levels, where the gameplay is more challenging, with no replenishing sun unless specific plants are used, the backyard is visited, with a pool added, and the final levels are nighttime pool levels (where fog fills the right half of the screen except when specific plants are used), a lightning storm level in pitch black (except when illuminated by occasional flashes of lightning), and rooftop levels (on the final level, the player must face a huge robot operated by a zombie known as Dr. Zomboss). At set points throughout the game, the player is either warned through a letter by zombies or addressed by Crazy Dave to prepare for an ambush, where the game takes on a bowling style, using Wall-nuts to bowl down zombies, or a modified version of regular levels, where random plant types come up on a small selection, and the player can use the plants without spending sun.
The player starts with a limited number of seed pack types and seed pack slots that they can use during most levels. The number of slots can be increased through purchases with in-game money. At the start of a level, the player is shown the various types of zombies to expect and given the opportunity to select which seed packs to take into the level. Several plants are nocturnal, such as mushrooms, having a lower sunlight cost, and are ideal for nighttime levels. Certain plants are highly effective against specific types of zombies, such as the Magnet-shroom, which can remove metallic items from a zombie, such as helmets, buckets, ladders, and pogosticks.
The zombies also come in a number of types that have different attributes, in particular, speed, damage tolerance, and abilities. Zombies include those wearing makeshift armour, those that are able to jump or fly over plants, and a dancing zombie which has different designs depending on the version that is able to summon other zombies from the ground. At various points, the player will be inundated with a huge wave of zombies.
If a zombie reaches the end of a lane for the first time, a lawnmower at the end of that lane will shoot forwards and destroy all the zombies in that lane. However, if a zombie reaches the end of that same lane for a second time, it will reach the player's house. When this happens, the music changes and the other zombies stop moving while that zombie enters the house. Crunching sounds will be heard, accompanied by a scream and a message saying "The zombies ate your brains!" The game will then end and the player can decide whether or not they will try again.
The primary game mode is a single-player, multiplayer, and Adventure Mode in which the player can earn money to spend at an in-game store to buy new seed packets and other bonuses.
The game also features extra modes that are unlocked as the player progresses through the main adventure. These include a Survival Mode with hard or normal mode, a Puzzle Mode which includes I, Zombie Mode and Vasebreaker Mode, and a selection of Mini-Games which include zombie-themed versions of other PopCap games like Bejeweled. The game also features a Zen Garden, where players can care for plants they acquire from successes in gameplay. Players can also buy other kinds of zen gardens in the in-game store. The in-game store also carries items that help with the Zen Garden. The PlayStation Network and Xbox Live Arcade versions of the game includes 5 multiplayer modes, both co-operative and competitive, additional mini-games, and a virtual house where players can show off their achievements to friends.
Plants vs. Zombies director George Fan intended on balancing the game between a "gritty" game and a "sickeningly cute" game. Strong strategic elements were included to appeal to more experienced gamers, while keeping it simple to appeal to casual gamers, without many tutorials. He was inspired to make it a tower defense game after both thinking of a more defense-oriented version of a previous title of his, Insaniquarium, and playing some Warcraft III tower defense mods. While he was looking at the towers in Warcraft III, he felt that plants would make good towers. He wanted to bring something new to the genre with Plants vs. Zombies, and he found common tower defense game play elements such as mazing and juggling to be too awkward, causing him to use the five- and six-lane set-ups that were used in the final version. The game was initially going to be called Weedlings, but as the tower defense concept took off and the personality of the game as a whole evolved, the title was later changed.
Fan included elements from the trading card game Magic: The Gathering while teaching his girlfriend Laura Shigihara how to play it, showing her how to customize their decks. That inspired him to include the seed packets as opposed to using a conveyor belt that produced randomly selected plants, due to the complexity of this system. Another influence on Plants vs. Zombies besides Warcraft III and Insaniquarium was Tapper, crediting the use of five lanes to this game. Various members of PopCap Games contributed to the development of Plants vs. Zombies through an internal forum where they gave feedback.
Some of the characteristics that defined Insaniquarium influenced the development of Plants vs. Zombies. Players advance in a similar pace by receiving new plants. Also, the way plants are chosen at the beginning of each level was derived from the way pets are chosen in Insaniquarium. Other inspiration for the game's mechanics came from the film Swiss Family Robinson, especially where the family defends against pirates. This was the inspiration for the Potato Mine; Fan stated that it was satisfying to watch a zombie step on the mine, being defeated and covered in mashed potatoes.
The team wanted to bring back the aliens from Insaniquarium, but in the end they were changed to zombies, which players could react to more easily because of how slowly they moved. Fan's favorite zombie was the Pole Vaulting Zombie, due to the hilarity involved when a player encounters it for the first time, using a specific example where a player tries to block it with the Wall-Nut, only to have the zombie jump over it.
During development, it was discovered that newcomers to the genre of real-time strategy may have a hard time learning the concept behind sun collection. So, the price of the income generating sunflowers was dropped from 100 to 50 to encourage players to buy them over the attacking peashooter. As a result, the balance between plants and zombies had to be restructured—a move that Fan said was definitely worth the effort. Programmers focused on Adventure mode for much of the first year of development. Upon finishing some items ahead of schedule, one of the programmers, Tod Semple, began working on ideas that would later be used for the minigame section. Some ideas for the puzzle mode section would later be tweaked and moved into adventure mode; "Vasebreaker" and "I, Zombie", for example, came from single-level minigame concepts. During testing, Fan found that minigame and puzzle modes seemed to detract from the focus on Adventure mode, so some of the additional modes and minigames were locked requiring advancement within adventure mode to become unlocked.
Fan stated that every game he worked on had only him designing the prototype, adding that he used to draw a lot before he made games, where he made pixel art. The final designs of the zombies and the first plants are similar to how they were initially. After searching for an artist, they discovered Rich Werner, who Fan thought clicked with what he intended for the design. He attributed the intrigue of the design to its animation scheme; Tod Semple suggested that they animate it in Flash and export it into the game. Fan worried that this would look like it was cut out from paper, and would resemble South Park too much, but was satisfied in the end, attributing this to Semple and Werner's talents.
Fan was most proud of the Tall-nut, Torchwood, and Cob Cannon plants. He explained that the Tall-nut has character, citing its "determined gaze" and how it sheds a single tear when hurt. Laura Shigihara could not stand to see this, and protected it with a protective plant called a Pumpkin, which can protect plants inside it. He felt that the Torchwood - which gives Peashooters flaming ammunition - required players to think of how plants interacted with each other. Another favorite plant of Fan's was the Squash, due to how its name suggested its purpose; to squash things. A plant was proposed that is similar to the defensive item Umbrella Leaf, which would be planted above other plants to protect them from airborne zombies. However, it was difficult to visualize their positions.
- Cultural references
Plants vs. Zombies uses many cultural references in its names of stages and others. The gravestones' inscriptions ("Expired", "Ceased to Exist", "Just Resting", etc.) were taken from Monty Python's "Dead Parrot sketch". Three of the mini-games—"Zombiquarium", "Beghouled" and "Beghouled Twist"—take their names from two other PopCap games (Insaniquarium, Bejeweled and Bejeweled Twist respectively. Two levels in "vasebreaker" puzzles, "Scary Potter" and "Ace of Vase", take their names from Harry Potter and Ace of Base. Similarly, the "I, Zombie" (a reference to Isaac Asimov's "I, Robot") puzzles have levels called "Dead Zeppelin" (resembling Led Zeppelin) and "All your brainz r belong to us" (a play on the gaming meme "All your base are belong to us"). The name of the Torchwood plant is a reference to Doctor Who and its spin-off show Torchwood.Originally, the dancing zombie resembled Michael Jackson from the short film "Thriller". Though the Jackson-inspired zombie was present in the game before Jackson's death, the estate of Michael Jackson objected to its inclusion more than a year after his death; PopCap agreed to remove the Jackson-inspired zombie and replaced it with a more generic disco-dancing one for all future patches and releases of the game. A "disclaimer" in the game's almanac states "Any resemblance between Dancing Zombie and any persons living or dead is purely coincidental." Some Plants vs. Zombies advertisements parody controversial Evony ads, showing a drooling zombie instead of a voluptuous woman.
A planned name was Lawn of the Dead, a pun on the title of the George A. Romero zombie film Dawn of the Dead. For legal reasons it was changed to Plants vs. Zombies. It spent three years in development, and was released for the PC on 5 May 2009. Since it was released, it has been announced for multiple platforms, including PlayStation 3's PlayStation Network, Xbox 360's Xbox Live Arcade digital distribution service, Nintendo DS, and iOS.
The song "Loonboon" was inspired by composer Laura Shigihara's cat, which they named Metroid. She explained that the stage she was composing for was frantic, so she watched Metroid as he ran around the house, jumping off walls and playing with his toy mouse. "Brainiac Maniac" was inspired by older Capcom games, specifically those in the Mega Man series, describing its songs as melodic and complex. She was inspired to make the Plants vs. Zombies music video by her desire to make a theme song for the game. She specifically chose the Sunflower to be the one singing by wanting to have it communicating with the zombies. She later suggested that it be made into a funny flash video, and Rich Werner and Tod Semple, an artist and programmer, respectively, from PopCap came down and worked on it. Once it was completed after two weeks of work, the PopCap marketing team enjoyed it enough that it was used it as a marketing tool. Previously, there were no plans to release the soundtrack as a stand-alone item, but Shigihara stated that she wished to do it, so she thought there was a good chance of it. In November 2010, Shigihara released the soundtrack through her Bandcamp page.Individual tracks are sold at USD1 per track or US$10 for the full album. It comes with a cover art designed by George Fan.
Plants vs. Zombies itself was referenced in "The Passing" campaign of Valve's fellow zombie game Left 4 Dead 2, in which the player can stumble upon in-game graffiti attributed to the character of Crazy Dave. A five-level quest chain culminating in a quest entitled "Lawn of the Dead" in the massively multiplayer online game World of Warcraft: Cataclysm is based on Plants vs. Zombies, using Warcraft elements to recreate the gameplay. Blizzard Entertainment had contacted PopCap about the inclusion, and Laura Shigihara was able to record some new music for the Warcraft version of the game.
The soundtrack for Plants vs. Zombies was composed by Laura Shigihara. It borrows elements from the pop music genre, as well as console chiptunes. Before the inception of Plants vs. Zombies, Director George Fan asked Laura if she would like to compose the music for his next title after following her for some years. She accepted, owing to his creativity. Shigihara described the music as "macabre, yet goofy". Using the night stage as an example, she used a combination of "Big Band" and swing beats with "several haunting and serious melodies". The songs "Loonboon" and "Brainiac Maniac" were written towards the end of production. The song "Ultimate Battle" also appears in the game Melolune. She stated that these were reactionary songs that she wrote to fit the feel of the game after having played through it twice. She tried to make the game have a Danny Elfman feel to it, while mixing in melodic tunes and funky beats. She describes a song early in the game, which uses marching band percussion and swing beats. She described another one which used techno beats with organic sounds. Shigihara also composed and performed the music video shown during the credits of the game, titled "Zombies on Your Lawn".
In late 2012, PopCap announced that they were working on a sequel to Plants vs. Zombies, but the status was in doubt shortly after the announcement when the company went through a period of layoffs. Plants vs. Zombies 2: It's About Time was released August 15, 2013 as a free-to-play title, and was a time-limited exclusive title for iOS systems before moving to other systems such as Android and the Xbox 360.
In May 2013, the Facebook game Plants vs. Zombies Adventures was released by developer PopCap Games and publisher Electronic Arts. The gameplay is a tower defense game, players no longer have to defend a single home in front of the zombie horde, and travel to new locations and to engage with new characters. On July 14, 2014, it was announced that Plants vs. Zombies Adventures will be closing down on October 12, 2014. The Facebook game was removed by November 2014.
In 2014, Plants vs. Zombies: Garden Warfare, a multiplayer third-person shooter based on Plants vs. Zombies, was released for Xbox One, Xbox 360, and Microsoft Windows,PlayStation 3, PlayStation 4, also as a sequel.
