What platform hosted Plants vs. Zombies Adventures at launch?
Answer
Plants vs. Zombies Adventures launched on Facebook.
The spin-off was announced in March 2013 and released on May 20, 2013, as a social game built for Facebook. It expanded the familiar tower-defense formula with new locations, additional plants, and an in-game farm where players grew more plants.
It is easy to confuse Adventures with the main Plants vs. Zombies game or later mobile releases. The original game arrived first on personal computers in 2009, while Plants vs. Zombies 2 debuted on iOS in 2013. Adventures was instead designed specifically as a browser-based Facebook experience, not an Xbox, Steam, or standalone iPhone release.
The Facebook game did not remain online permanently: Electronic Arts announced its closure in July 2014, and the service shut down on October 12, 2014. That makes its launch platform a useful historical detail about the period when social-network games were a major part of casual gaming.
