Plants vs. Zombies: Infinite Generation/Missions and Quests

Being an MMORPG, Plants vs. Zombies: Infinite Generation contains several campaigns with missions and quests to guide the player through the game's story.

This page will cover both a brief synopsis of all playable campaigns and quests along with the mechanics behind mission spaces.

Mechanics
Almost all missions involve traveling from one point to another while fighting enemies, usually into areas that are either private (meaning a pre-formed team is required to bring others into the area with the player) or only accessible during that mission. Usually, a boss is also fought at the end, and the mission concludes with either a reward or advancing the quest chain it is linked to.

Restricted Respawning
Restricted respawning is a mechanic activated during tense moments in a mission. While it is active, the player's respawn timer is extended from 5-15 seconds to 30 seconds (60 seconds in dungeons and infinitely in raids), and if no players are alive, the mission restarts from the most recent checkpoint after a three-second grace period. When playing in teams, players are encouraged if not mandated to revive others to keep each other in the game.

If all players die and fail to respawn during the grace period while the modifier Time Abyss is active, the entire activity will be aborted, forcing a restart from scratch.

Mission-specific Mechanics
Some missions have unique mechanics that must be utilized to progress forward. These will be noted in the individual pages for each mission.

Difficulty
Some missions, usually repeatable activities, allow the player to choose a difficulty level. This raises the power level of all enemies in the mission, adds harder modifiers, and most importantly gradually skews the loot table in favor of rarer rewards.

In the case of more complex missions such as secret levels or raids, choosing the Heroic difficulty may alter the course of the mission or the mechanics used.

All modifiers for each difficulty listed below stack on top of the previous difficulties' modifiers. Note that depending on the specific mission, the modifiers endemic to each difficulty and above may be changed or absent. Note that attempting to play a mission while having a power level deficit of over 50 points will reject the player.

Modifiers
When replaying missions and other forms of encounters on higher difficulties, modifiers may be introduced to contribute to said higher difficulty. They may help or hinder the player depending on their nature and how they are used.

Generic Difficulty Modifiers
These modifiers are universal to all elective difficulties, but may appear regardless in certain quest missions. Some modifiers are only active on higher difficulties by default.

Generic Elemental Damage Modifiers
These generic modifiers boost incoming and outgoing elemental damage based on the most prevalent damage type in the encounter.

One or more of these modifiers are enabled by default in all Heroic encounters and higher:

Destination Modifiers
These modifiers boost incoming damage based on the world the mission takes place in. They are active on all non-matchmade Heroic+ activities.

All of these modifiers calculate boosted damage after factoring in damage boosted by other modifiers and abilities.

List of Campaigns

 * The Virtual Warrior EXA is Born: LEAF's high command ordered you conscripted into their forces after the incident with Rey.
