Context-sensitive information – shown only as it becomes important, such as tutorial messages, special one-off abilities, and speech subtitles.Usually shown only when driving one of these. Speedometer/tachometer – used in most games which feature user operated vehicles.Mini-map – a small map of the area that can act like a radar, showing the terrain, allies and/or enemies, locations like safe houses and shops, streets, etc.This might also include the character's current task or quest. Game progression – the player's current score, money, lap, or level (as in stage or as in experience points).Menus – Menus to exit, change options, delete files, change settings, etc.Icons and/or text may appear in the HUD to indicate other actions that are only available at certain times or in certain places, to show they are available to perform and which button performs it for example the text 'A – open door' may be displayed, but only when the character is near a door. This can include when the ability will become usable again, such as ammunition, magic points, or some other type of 'charge up' timer. Capabilities – gameplay options that are often accessible by the player during gameplay, such as available weapons, items, or spells.Can show other available weapons, and objects like health packs, radios, etc. Weapons/ammunition – Most action games ( first- and third-person shooters in particular) show what weapon is being used, and also how much ammunition is in it.Some games may also display the real time. Many HUDs also use time displays to show the in-game time, such as the current time of day or year within the game. It may also be a timer counting up to records such as lap times in racing games, or the length of time a player can last in games based on survival. Time – This may be a timer counting down the time limit or the time left until a specific event.In many fighting games, there are often two health bars on the top of the screen which often depletes to the middle (sometimes the opposite direction) with every punch or kick the player/enemy inflicts to their opponent. Also, in many (but not all) first- and third-person shooters, when the player is damaged, the screen (or part of it) flashes briefly (usually in red color, representing blood) and shows arrows or other similar images that point to the direction the threat came from, thus informing the player from which direction the enemies are attacking. Real-time strategy games usually show the health of every unit visible on screen. Health/lives – this might include the player's character and possibly other important characters, such as allies or bosses.Most of them are static onscreen so that they stay visible during gameplay.

While the information that is displayed on the HUD depends greatly on the game, there are many features that players recognize across many games. The HUD is frequently used to simultaneously display several pieces of information including the main character's health, items, and an indication of game progression (such as score or level). It takes its name from the head-up displays used in modern aircraft. In video gaming, the HUD ( heads-up display) or status bar is the method by which information is visually relayed to the player as part of a game's user interface. The Nuclear Dawn HUD displays the character's health, weapon ammunition and compass heading, while also displaying the map of the area in the top-right corner, and a circular marker pointing to the player's destination.
