A Heads-Up Display, or HUD, is the name given to the screen viewed by the player of a first-person shooter game.
In the Call of Duty series[]
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 Hardcore multiplayer modes, the HUD is limited to nothing but the kill-feed and a mini-map, which only appears when a UAV, Spy Plane, Blackbird, Advanced UAV, Orbital VSAT or H.A.T.R. 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. The Realism mode in Call of Duty: Modern Warfare and Call of Duty: Modern Warfare II limits the HUD effectively.
