The core gameplay of Dissidia Duellum Final Fantasy in a broader context is defined as a 3vs3 Team Boss Battle Arena, combining PvPvE (Player versus Environment versus Player) mechanics designed specifically for mobile platforms. Here are the key system details:

1. Objective-Based Gameplay

• Boss Race: Unlike previous entries focusing on defeating opponents, the main goal here is to compete to defeat the stage boss the fastest within approximately 5 minutes.
• Winning Conditions: The team that depletes the boss's health (separate for each team) first, or the team with the lowest remaining boss health when time expires, wins.

2. Bravery System and Damage Mechanics

• Bravery Burst: Normally, bosses are invincible with protective barriers. Players must accumulate Bravery Points (BP) up to 9,999 to activate Bravery Burst, the only state where they can deal damage to the boss.
• BP Accumulation: There are two main methods:
  1. Crystal Purification: Defeat monsters around corrupted crystals on the map (e.g., Ginza area) and stand nearby to purify, granting BP to the team.
  2. PvP Combat: Attacking or defeating opposing players steals their Bravery Points, preventing them from entering Burst mode quickly.

3. Roles and Team Synergy

Characters are divided into four main roles for balanced strategic play:

• Melee: Frontline attackers who clear monsters and disrupt enemies (e.g., Cloud, Gaia).
• Ranged: Attack bosses from a safe distance (e.g., Terra, Prompto).
• Agile: High mobility characters controlling the map and disrupting enemy crystal captures (e.g., Lightning, Zidane).
• Support: Provides healing, buffs, and shares Bravery Points (e.g., Krile, Warrior of Light).
• Burst Chain: If multiple team members enter Burst mode and attack the boss together, a Team Combo or Burst Chain occurs, multiplying damage significantly.

4. Controls and Technical Architecture

• Portrait Orientation: The game is played vertically for one-handed convenience, using a virtual joystick for movement, with characters automatically attacking nearby enemies.
• Ability Usage: Activated by dragging ability icons upwards, showing range and direction before release.
• Controller Support: To improve gameplay and camera control, external controllers (e.g., PS5 or Switch Pro) are supported from launch.

5. Ability System and Customization

• Deck Setup: Each character can equip 5 abilities (1 main slot + 4 support slots).
• Gacha Integration: Character strength depends on the rarity of skills (N to UR) obtained from gacha, which directly boosts stats (ATK, DEF, HP).
• Job Medals and Memoria: Additional systems for customizing passive effects and specialized stats (e.g., movement speed or critical rate) according to player preference.

In summary, the core gameplay of Dissidia Duellum emphasizes "objective-focused cooperation" over traditional one-on-one combat.
