Vine Gateway

Vine Gateways are a new plant introduced in Project Z. They are unlocked after the ninth level of Suburbia Streets is beaten.

Ability
When Vine Gateways are placed, you must put two in different places. When a zombie enters one of the paired Gateways, it comes out the other. This can be used in conjunction with trap plants such as Potato Mine and also to divert zombies out of a less defended lane.

Strategies
Vine Gateways can be utilised in a variety of different ways to the player's advantage but if used wrong can give zombies a boost towards your defenses. Something that needs to be kept in mind is that if you are using a Vine Gateway to send zombies from a weakly defended lane to a stronger one, zombies that enter the stronger lane will be transported to the weaker one, as the Gateways work both ways.

Trivia

 * Vine Gateways were inspired by the Portal franchise.
