Non-playable character

Template:Realworld Non-Playable Charachter, or NPC refers to a character in a video game whose actions cannot be controlled by the player and is a vital part of the stroyline.

NPC's are only seen in gameplay with the player, and are usually either allied or neutral to the player. Classically, they feature unique triggers and dialogue that differentiate them from "normal" allies because they are vital to the development of the game's storyline.

In Halo: Combat Evolved, there are only two NPCs, Captain Jacob Keyes and 343 Guilty Spark. Keyes is only seen a few times, but if he is killed, the mission is failed and you must restart the level. 343 Guilty Spark is invincible and immune to any attacks on him during the game.

In Halo 2, all NPCs are invincible. They usually fight alongside the player and lead allies into battle. Most of the time they are also armed with stronger weapons and feature unique dialogue that is integral to the storyline.
