List of Half-Life 2 entities

This list sorts all Half-Life 2 entities by the FGD that added them. The list was checked by hand with and the HL2 FGDs. Entities that don't actually exist (like ) are omitted, as are entities that were only added in the episodes. Entities are listed alphabetically, with mini-headers for their prefixes.

These entities weren't in any FGD. They might be broken or unused, or it might not be a good idea to place the ent directly in a map.
