Battlez is a game mode in Plants vs. Zombies 2 that was introduced in the 6.6.1 update. This mode is unlocked after getting the Map of Space-Time-Ness from Ancient Egypt - Day 1 and obtaining at least six plants.

Gameplay
To start a match, the player has to use a Gauntlet. Gauntlets can be bought with gems. However, every four hours, the player receives a free play. The player can press the 'FREE GAUNTLETS' button, which is located to the left of the Play Button, to watch an advertisement and obtain a free gauntlet. Up to four free Gauntlets per day can be obtained by watching ads.

When an opponent is found, the player will usually choose five plants, with the first slot reserved for the plant of the week. Once the plants are chosen, the player is set in the Last Stand format, then after setting-up, the "battle" begins. The player gains points based on the distance the zombies are away from the house, and their starting health. Zombies in the yellow zone are worth their full potential of points, while zombies in the red, blue, and brown zones being worth 60%, 40%, and 20% of their potential respectively. Points can also be scored by removing most forms of armor through any method. Zombies buffed by Cardio Zombie are worth extra points. Destroying Gravestones and Surfboards are also worth a small amount points.

This mode is time-based, and the zombies have significantly more health, with higher leagues having even higher health. Zombies can often survive multiple instant-kills. Zombies will also eat significantly faster causing most plants to be eaten instantly. The faster the player kills the zombies, the more health they will have. Having a non-defensive plant getting eaten will result in a penalty, causing the zombie health to be reduced and therefore significantly reducing the score they will give. Having a sun-producing plant getting eaten or manually launching a Lawnmower will result in a big penalty, and if a zombie activates a mower, this will result in a huge penalty. Winning a match of Battlez is brought about by getting a higher score than your opponent, and grants the player five Crowns, whereas losing a match only yields one crown. Surrendering will count as a loss, but will grant no crowns.

As the player wins matches, they will collect rewards from a reward streak, found under the Play Button. The rewards get better as the player wins more consecutive matches. As of a new update, the reward tick will always stay at the 3rd reward, unless it is not possible (for example, if the player has collected the first reward), while the rest of the rewards move along to the left. If the player breaks a streak, they can pay 10 gems to retain it, with the cost increasing by ten gems per retain, and caps at 250 gems. If they reset their streak, the cost to retain goes back to 10 gems. After a win streak of a multiple of 98, the rewards will reset, but will increase a multiplier by one, so a streak of 99-196 will be worth twice as much as a streak of 1-98.

Currently possible rewards for the Reward Streak:
 * Coins
 * Premium Piñata
 * Mints
 * Featured Plant of the Week seed packets or Featured Pinata
 * Gauntlets

Each week, there will be a different type of tournament that the player will have to compete in. Each type of tournament has its own way of changing the gameplay (the change can be quite minor, however). For example, a tournament can shorten the time it takes for a match to finish. It could also be quite major (for example, from 17th July - 19th July 2018 Grapeshot's Double Shot Tournament lasted 2 days and the rewards were drastically decreased).

Also, this mode also has several different leagues; the player gets promoted if they place top 3 in their league by having a number of crowns higher than all but two or less other players in their league. If they are placed in one of the last three spots, they will be demoted to the league before that one (this is not the case in the lower leagues, where special methods are required to be demoted). Several gems, mints and coins are rewarded in promotions.

It has been noted that this mode does appear to be lacking a "real" matchmaking feature that pairs you with another player fairly. There have been reports of people that had low-leveled plants to still be paired with a person with max-leveled plants or still high-leveled plants. Players can also be paired against bots that solely calculate their score based on the players.

Trivia

 * According to a PopCap community manager (referred to Haemophilus EA on Reddit), the player is not actually fighting against other players in real-time, rather, just "ghosts". The score progression seen in gameplay is just a replay of the "ghost" player's previous Battlez round.
 * Other affirmations that support this are:
 * You can spend infinite time on the pause menu, Choose Your Seeds screen, and the Last Stand defense preparation stage.
 * The Turbo Button can be used.
 * There is no feature in which time must be synchronized with the other player due to lag, pausing the game or the Turbo Button.
 * A list of over 9900 names for these "ghost" opponents may also be found here.
 * Some bot names also include Solar Flare, Spudow and Rose from Plants vs. Zombies Heroes.
 * It is unknown what happens, and how many Crowns will be received if the players tie at the end of the match.
 * However, it has been noted that if the players tie during a match, the player who caught up will have an enlarged score number. The player with a higher score would also have an enlarged score number. This suggests that if the players tie at the end of a match, the player who caught up will win.Enlargedscore.jpg
 * When tapping on the Battlez icon, the Dark Ages Zomboss Battle intro plays, along with the boss music.
 * When being awarded for winning a match, no extra Crowns are given for obtaining higher scores or beating your opponent by a small amount.
 * This is the only mode in the game, other than Cannons Away where zombies cannot eat your brains. This is because when a lawn mower is activated, it is automatically regenerated. If a zombie somehow manages to reach your house, it will get instantly killed.
 * All upgrades, except for Wall-nut First Aid, Instant Recharge and Mower Launch, are disabled on Battlez.
 * Also, plants that are boosted in the Zen Garden will not have their boost in this mode.
 * Power Ups are disabled in this mode.
 * The player does not get points for the zombies destroyed by lawnmowers.
 * However, it scores points when it destroys a surfboard.
 * World exclusive plants cannot be used in this mode, even if there are special mechanics that can be affected by them.
 * Perfume-shroom cannot be used even if there are dinosaurs in the battle.
 * Hot Potato cannot be used even if there is ice blocks, octopi, or Hunter Zombies in the battle.
 * Thyme Warp cannot be used even if there are Neon Mixtape Tour zombies in the battle.
 * Before the 6.9.1 update, Neon Mixtape Tour zombies in this mode did not have their jam abilities.
 * In the textures for the trophies that identify for each league, there appears to be an unused crystal-like trophy.
 * The setting in this mode is the same as Player's House and Modern Day worlds, but in the style of Dark Ages.
 * This can be seen that if a zombie in this mode eats a boosted Hypno-shroom, it transforms into a hypnotized Dark Ages Gargantuar.
 * All the Flag Zombies that appear in this mode are Peasant Flag Zombies from Dark Ages.
 * Removing armor and destroying gravestones score points. However, removing graves using Grave Buster will not score points.
 * If the player manages to defeat all the zombies before the time runs out, the results screen will pop up, despite the amount of time remaining.
 * If plants are thrown into the air toward another tile (for example by a portal or Potato Mine's Plant Food effect) as time reaches 0:00, the player will see the plants 'jumping' off the screen as they receive their Crowns.
 * Lightning Reed's Brainstorm Tournament is the first tournament where the special plant is a free plant. The second is Shadow Peashooter's tournament.
 * Sometimes, in Electric Currant's Garden Party and Snow Pea's All-out Tournament, if a zombie is killed over a rail, very few points will be given, that is, the points that would be obtained in the lowest scoring zone, even if the rail was in the highest scoring zone.
 * In Electric Blueberry's Brainstorm Tournament, if a kicked Super-Fan Imp lands on one of Dave's mold colonies, it will blow up, scoring points according to where it landed. The points will only be scored after it has disintegrated.
 * Like Modern Day and Piñata Party, Battlez has some environment modifiers from other worlds present in some of its tournaments, such as tombstones, evil potions, dinosaurs, and more.
 * Surprise attacks from other worlds are also present, such as sandstorms, bot swarms, parachute rains and more.
 * Bombegranate's Garden Party Tournament, Explode-O-Nut's All-Out Tournament, Gold Bloom's Garden Party Tournament and Power Lily's Tournament happened twice.
 * The first Grapeshot's Double Shot Tournament is identical to Caulipower's Escalating Tournament, except that Caulipower was replaced by Grapeshot as the plant of the week.
 * Blover is restricted from most tournaments in Battlez.
 * This is because Blover can be used to insta-kill any zombies when combined with plants such as Primal Peashooter.
 * Battlez requires internet to play. However, if a player has entered a match and disables internet connection, it is still possible to play the entire match. At the end of the match, the player will be promoted to reconnect to internet or exit Battlez. If it was a win, exiting Battlez will not make the player lose their streak.
 * In Snow Pea's All-Out Tournament, it is possible for plants to exist under Zombie Kings by planting on an empty minecart and moving it under the Zombie King.
 * Arma-mint's Garden Party Tournament was the first tournament where the special plant is a Power Mint.
 * Contain-mint's Tournament was the first tournament that had a Buffz & Bruisez feature in it.
 * During last stand setup, you can dig up pre-placed Plants (If there's any) to get more Sun.
 * So far, there have been no tournaments that feature endangered plants, planting limits, or flowers.
 * In Parsnip's Tournament, you can earn seed packets for Shadow Peashooter from the Reward streak, despite not being the plant of the week.
 * In Jack O' Lantern's Tournament, there are frozen level 10 fire plants pre-placed, which is ironic because fire plants are usually immune to freezing. Additionally, the Plant Food tombstones are extremely tough, requiring 30000 dps to break them.
 * In Missile Toe's Tournament, the frozen plants that are seen on the lawn are maxed out. This can be seen as the projectiles are different as well as the Sunflowers producing more sun.
 * In Gold Bloom's Tournament, the players are given plants that are maxed out instead of choosing them.
 * In Starfruit's Tournament, the seed selection screen fools the players that they'll be fighting only Basic Zombies and Hamsterballs. It is proven that PopCap lied when the match starts, the incoming zombies are the same from Electric Peashooter's Tournament, excluding the Cardio Zombie.
