NPC

Jackson Hall is likely the first survivor NPC you will meet in TLS:UC

An NPC, or Non Playable Character, is a fictional character not controlled by a player. In electronic games, this usually means a character controlled by the computer. In traditional tabletop role-playing games, the term applies to characters controlled by the Gamemaster. (Though they are a participant in the game, a Gamemaster is usually not referred to by the technical term "player.")

The Last Stand

Fellow survivors and zombies are NPCs.

The Last Stand 2

Just like the previous game, survivors and zombies are NPCs.

The Last Stand: Union City

Survivors and zombies, are, again, NPCs. Most survivor NPCs can be interacted with, to a degree. They grant the player certain quests or supply them with information (or simply babble about their experiences). Two NPCs — Hank and Kelly — are able to become survivor companions.

The Last Stand: Dead Zone

Zombies and some survivors are NPCs. Survivor NPCs often give tasks. Two notable survivor NPCs are a Russian trader named Ivan and a mysterious survivor known only as X.
