Crucible

"What is the Crucible? Before the days of the City and the Iron Lords, it was a place to pursue vendettas. To battle for territory, and pettier reasons. The whole world was a Crucible Arena. The Crucible today? To Cayde-6, it's a gambler's paradise. To Zavala, it's a resource sink where equipment goes to die. To Ikora, it's home—though she would never admit it. Partial answers. The tactics and techniques that will save us in wars to come are birthed in the Crucible, during live-fire training. The Vanguard are so preoccupied with their own agendas they're missing the Vanguard of tomorrow rising right before their eyes."

- Lord Shaxx

The Crucible is the player vs. player game mode in Destiny and Destiny 2. Items bought or earned in the game can be used more effectively in the Crucible, and weapons/armor received elsewhere can also be used in the rest of the game. The Crucible will sometimes randomly reward players after matches, regardless of rank after the game, while players can also purchase weapons from the Crucible Quartermaster as well as Armor and Shaders from Lord Shaxx and Lord Saladin.

The mode returns in Destiny 2, but the player cap was been reduced to 8 players at launch, but was later raised to 12 in all quickplay and Iron Banner modes. The HUD has been reworked to give players information on their opponents, such as whether they have their super attack ready or if they’ve picked up ammo for their power weapon.

Destiny
All Crucible maps are completely separate and unique from explorable locations in the game. Each map will feature nearly all game modes on them with exceptions made to much larger maps made to be used in the mode Combined Arms. Players start out with ammo for their Primary weapon, and a small amount for their Special weapon, though throughout each map, there are multiple chests of Special ammo, and Heavy ammo chests appear in the middle of the match that replenish more slowly than Special ammo chests. After Hotfix 2.5.0.2, all players lose their special ammo after dying, and must wait for a crate to spawn. These changes did not affect sidearms, the No Land Beyond or the Universal Remote. Anyone who opens heavy chest gains Heavy ammo for themselves, and any teammates that are close by, but can only be used once per game, with the exception of Mayhem game modes. Players are also restricted from using ammo syntheses, since it could potentially lead to an unfair advantage for one team over another.

Level advantages are normally disabled in the Crucible in order to have an even playing field. The two exceptions to this are the Iron Banner and the Trials of Osiris, where level advantages are enabled. Private matches can also be set up to have level advantages enabled. This means that having high-level gear matters in those events. Also, Crucible bounties can be completed in Iron Banner matches, whereas Iron Banner bounties must be completed in Iron Banner matches. The Trials of Osiris weekend Elimination tournament also has special bounties that refresh every day of the event. In addition to standard Crucible bounties, every week Lord Shaxx has a set of weekly bounties that are more difficult to complete, with several objectives to complete instead of just one. Completing these weekly bounties will reward a Nightfall-tier reward such as a legendary or exotic piece of gear, as well as various materials.

The "Mercy Rule" was implemented with the release of The Taken King. This allows matches to end early when one team has more than approximately 2/3 more score than the opposing team. When the rule is enacted, no more players may join the match and the game clock is forwarded to 10 seconds. After those 10 seconds, the match will end normally. All players will receive their end of match rewards and return to matchmaking, splitting up those teams so they can't get matched against that same team. Bungie will update the rule's identification function over time. Players who are successful in forcing a mercy rule will receive a special medal, but no additional rewards.

Destiny 2
In a significant change from Destiny, all Crucible playlists in Destiny 2 used to be fought by two teams of four players each, except for Iron Banner which is six versus six. This was changed and now almost every game mode is 6v6. Power weapon ammo distribution has been reworked: Power ammo is now granted more frequently at various terminals across the map, with obtainment being locked to the team of the player who first opens the terminal for a few seconds after, and Power ammo is lost on death. However after patch 1.1.4 a player killed while holding Power ammo will a drop brick of Power ammo containing 50% of their remaining ammo. Completing matches earned both gear and reputation tokens (with additional rewards dropped if players use a Boon of The Crucible consumable) to be redeemed for additional rewards at the appropriate vendor. With the start of Season 12, reputation gains became automatic, and tokens were phased out. Furthermore, no mode or event has level advantages enabled, ensuring that player skill is equally as important as obtained gear and loadout. The Mercy Rule from Destiny is enabled in all Quickplay modes, including Mayhem.

Special events

 * Iron Banner: 6 vs. 6 endgame mode. The match type can vary.

With Season 17, Power no longer matters, tokens were removed and reputation is gained automatically similar to regular Crucible. Rift was also introduced as a mode of play in Iron Banner, for this season.
 * Trials of Osiris: Special Elimination-style mode accessed only through a Trials Passage. Players attempt to wipe out all three players on the other team. Teams are eliminated from a flawless completion after 1 loss, however they are forgiven 1 loss per run with a Passage of Mercy.

This game mode replaced the Trials of the Nine.

Discontinued modes

 * Breakthrough: 4 vs. 4 mode in the Competitive playlist. Players must battle to control the Breaker, which allows them to hack the enemy team's Vault. Once the central Breaker is controlled, it can’t be recaptured and the other team must defend the Vault. The attackers need to capture the Vault before time expires in order to win the round, or else the defenders will earn the point.
 * Countdown: 4 vs. 4 mode in the Competitive playlist. Similar to King of The Hill where Guardians must defend a central charge from an enemy team.
 * Supremacy: 6 vs. 6 mode in the Quickplay playlist. A team deathmatch mode where players fight and collect crests that drop in order to confirm their kills. Once time expires, the team with the most points wins.
 * Trials of the Nine: Highly competitive 4 vs. 4 endgame mode. The match type can vary. The goal is to earn the best possible rewards by winning 7 matches in a row with zero losses. Teams must start over after reaching 3 losses. Only a single win is necessary to gain access to The Third Spire, but only a team with a flawless 7-win record can reach The Third Spire's apex.

Trivia

 * According to Shaxx and Saint-14 during the Season of Dawn, the Crucible used to be a method where Guardians could sort out their differences. This changed following the Twilight Gap, where Shaxx turned into the arena to forge better Guardians it is today.
