trigger_finale is a model entity available in Left 4 Dead series. It acts as trigger for the finale of a campaign and is capable of firing outputs for different stages of the finale.
In most cases, if this entity is represented as a model in the world (like the ham-radio), it would start disabled, because first the players would interact with a func_button tied to a prop_dynamic to play a voice line and then enable the actual trigger_finale.
If trigger_finale is not above the finale arena's nav mesh, the end of the escape route will be determined by the center of the all the nav areas marked with FINALE.

AltNames: This entity is also tied to finale_trigger.

Risk of Confusion:Despite the name starting with word trigger_ it's not a trigger brush entity but a button using a studio model

Note:This entity is not required for survival gamemodes. Anything that fires the ForcePanicEvent on the info_director will start survival finales.

Note:Spawning trigger_finale with a point_template as seen in map c5m5_bridge leads to poor VScript compatibility, especially for finale type detection by mutations. Using StartDisabled keyvalue and using the Enable input when needed is a better practice.
