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 needs to 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. Zombies in the (yellow zone) are worth the most and zombies in the (brown zone) are worth the least, with stronger zombies such as Gargantuars worth more points. Points can also be scored by removing most forms of armor through any method.

This mode is time-based, and the zombies have significantly more health, to a point where they could withstand multiple instant-kills. Zombies also eat significantly faster causing most plants to be eaten instantly. The faster the player kills the harder and more the zombies will be. 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.

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.

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.

List of Tournaments
* Plants that are normally restricted, such as Gold Leaf and Lily Pad, are excluded. + and - : They swap everyday.

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.
 * Only three Plant Food are given for any match, and the player cannot buy any additional Plant Food. However, Power Lily can be used to get more Plant Food. Additionally, in Snow Pea's All-out Tournament, players will start off with no Plant Food and Plant Food tombstones spawn throughout the match, allowing players to earn more than three Plant Food. Also in Starfruit tournament, the player starts with no Plant Food, getting them by killing zombies.
 * There are no zombies carrying Plant Food in this mode, except in Starfruit tournament.
 * The player does not get points for the zombies destroyed by lawn mowers.
 * 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.
 * During Strawburst's All Out Tournament, the only sun producing plant available is Solar Tomato.
 * A player will not gain a Crown upon surrendering, but will still gain a Crown if defeated when the match time is up.
 * 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 you can insta-kill zombies with low leveled plants using the Blover
 * 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 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.
