Heads-up display

A Heads-Up Display, or HUD, is the name given to the screen viewed by the player of a first-person shooter game. In real life a HUD would be a person's view through some sort of visual-aiding device, often the cockpit window of an aircraft or a helmet mounted display.

In-game
In the Call of Duty series, the HUD is not present at all times, and appears only when the player is low on ammo, sometimes when switching weapons or picking up a new weapon, and some other times. In the "Hardcore" multiplayer mode the HUD is limited to nothing but the kill-feed and a mini-map, which only appears when a UAV/Recon plane is called in. They will also still see the names of teammates, the symbol showing they are carrying a bomb/flag, and the amount of flags captured.

Examples of things seen on a HUD include:


 * Names of teammates
 * Compass
 * Location of objective (in Call of Duty: Modern Warfare 2 and Call of Duty: Black Ops single player)
 * Grenade indicator
 * Cross-hairs (if enabled)
 * Reload/low ammo indicator
 * Equipped weapon
 * Current stance
 * Mission updates (New objectives, game saves, etc.)
 * Ammo counter (in Call of Duty through to Call of Duty 3 and Call of Duty Black Ops it was just a simple numbered box, but in Call of Duty 4: Modern Warfare through to Call of Duty: Modern Warfare 2 it was a visual representation of each remaining cartridge)
 * Weapon pickup icon/Use function
 * Health bar (Call of Duty, Call of Duty: United Offensive, Call of Duty: Finest Hour, and Call of Duty 2: Big Red One)
 * Blood Splatter/Red Screen (Indicates health in Call of Duty 2 through to Call of Duty: Black Ops)
 * Damage indicator
 * Game hints
 * Subtitles (Single Player), team chat (Multi Player)
 * Callsigns (in Multi Player)
 * Time left/passed (in Special Ops)
 * Enemies killed/remaining (in Special Ops)
 * Current round (in Nazi Zombies)
 * Score (Nazi Zombies and Arcade Mode)
 * XP meter (Call of Duty 4: Modern Warfare through to Call of Duty: Modern Warfare 2 Multi Player)
