Force field

Force Fields are entities in ''Plants vs. Zombies 2: It's About Time. ''Force fields are strong pieces of technology that cover up an area. They are used as barriers for protection in any world. They were first encountered in the Far Future, year of 2323.

Variants
In Plants vs. Zombies 2: It's About Time there are currently only two types of Force fields, one controlled by the player it's allies, while the other are controlled by Dr. Zomboss' Zombies. Both of them work very similarly.

Plant Force Field
This force field is controlled by the player and there is currently only two ways to make it. One way is by feeding an Infi-nut some Plant Food, while the other is by gaining the Infi-nuts Plant Food Boost in the Zen Garden. When the force field is activated by the Infi-nut, it is projected directly infront of it. Killing the host (Infi-nut) will deactivate the force field, this also counts by shovelling it.

The force field can last a very long time but it can be destroyed, like any other force field. When the force field is about to collapse, it's light will start to spark and fade, and the force field can only be restored by re-feeding the host Plant Food. In Pirate Seas, using a force field on the edge can deflect Imps that are fired from an Imp Cannon, bouncing them back into the water. The Plants Force Field colour is blue, and it can cover 5 blocks down, on the lawn. This force field can be used in any world, but only after the Infi-nut is unlocked.

Zombie Force Field
Unlike the Plant Force Field, the Zombie Force Field is mobile, so it can constantly be moving. It can only be used by Shield Zombies and it can absorb any Plant Projectile, except for the Laser Beans lasers, which punch through the shield. The zombie force field can protect other Zombies in it's radius. When the force field collapses, the host (Shield Zombie) will become immobilized for a few seconds, then it will continue to move again with it's force field up.

If the host is killed, then the force field is disappear. The Zombies Force Field is purple and it can cover 3 blocks down on the lawn. This force field can only be encountered in the Far Future.
