trigger_finale is an e0 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 an 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.
It has a duplicate entity with a different name, which is thefinale_triggerentity.

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