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 (GTA 1 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 VC, also borrows GTA III's weapon icons, as well as the icons for the weapons introduced in VC (i.e. Pistol and SMG).
