A Heads-Up Display (HUD) is a set of indicators used in most games to show the player's current status in a game, such as the score, health and the life.
A HUD can be used to convey many different types of information, such as time, score (in some missions), money, health, armor, weaponry, ammunition, warnings (e.g. "wrong way" in a race) maps with blips and subtitles of conversations.
The HUD GTA games may display the following information:
- Weapon selected and amount of ammunition.
- Amount of health.
- Amount of armor.
- Mission title (GTA III onwards) when starting a mission.
- Oxygen remaining (GTA San Andreas) or Stamina (GTA Vice City Stories) when in water.
- Gang respect (GTA 2).
- Player character stats and skills (GTA San Andreas).
- Wanted Level. Starting with GTA San Andreas (except GTA Advance), the wanted level interface does not appear until the player has a wanted level.
- Time (GTA III and later) (in Grand Theft Auto Advance, only when on foot), indicated by a 24-hour clock.
- Vehicle speed (GTA Advance), in miles per hour. Replaces the time display when riding in a vehicle.
- The vehicle the player enters. In GTA V, the vehicle name displayed in the lower right corner includes the car manufacturer, as well as its category (ex. Albany Cavalcade, SUVs).
- The district the player enters.
- The street the player enters (Grand Theft Auto IV).
- Character's special ability meter (Grand Theft Auto V).
- Location Compasses, compass points to key locations (Grand Theft Auto to GTA 2).
- A radar, a small map of the player's current location (GTA III onwards). Altitude meters are also integrated into the radar for GTA San Andreas, The Ballad of Gay Tony, and GTA V.
- The mobile version of Grand Theft Auto: Vice City does not use the HUD from the original version of the game; instead the game uses and recolors the HUD of the mobile version of GTA III. The Fist, Pistol, MAC-10 (which uses the GTA III Micro-SMG icon), Flamethrower, Grenade, and Molotov Cocktail icons are reused from GTA III and are recolored pink and purple. The mobile version of Grand Theft Auto: Liberty City Stories, having the same weapons as GTA Vice City, also borrows GTA III's weapon icons, as well as the icons for the weapons introduced in GTA VC (i.e. Pistol and SMG).
