Lost City

Lost City is the eighth world in Plants vs. Zombies 2, released along the 3.6.1 and 3.7.1 updates.

This world was first revealed with the official trailer released on May 25, 2015. Then Part 2 was released on June 6, 2015.

After three weeks, Lost City Part 2 trailer was released on June 21, 2015, along with the developer diary two days later, on June 23, 2015, on the same day as the teaser parties and the release of Toadstool, the premium plant released alongside the second part of this world. Another 2 days later, Part 2 was soft released for Android devices. Next oday on June 9, 2015 the official update was released.

The timeline of this world has yet to be revealed, and it appears to be set in early Mesoamerica, but it also seems to take place on the beginning of the XX century, since the zombies come from a more modern era of exploration, and modern inventions like planes are present.

The main gimmick of this world are the Gold Tiles. When a plant is placed on a Gold Tile, it will immediately give the player 50 sun, and then produce another 50 sun every 20 seconds until eaten, crushed, or moved by the zombies. Replanting a plant on a Gold Tile no longer generates sun. Nothing special happens when the player uses Plant Food on a plant located on a Gold Tile.

Game description
''Discover the vanished city of gold, where sun is plentiful and misplaced zombies abound! Use special tiles for extra sun, for these treasure-seekers are no idol threat!''

Trap Tiles
In this Brain Buster there are two new types of tiles on the lawn which are activated by either plants or zombies who are on the top of it. Those can send either a jet stream of fire that affects the whole lane or send a moving rock that destroys everything in two columns. Using an already chosen set of plants, the player has to finish the level to move on. It has Days 22 and 28.
