Template:Entity

is a entity  available in.

This template goes at the top of every entity page.

Some notes

 * Don't use with   or   for . "since some/most Source games" sounds wrong.
 * If you have to use  or   for, specify the games using Template:Gamelistbox.   and   are the exact same except for one word.
 * cannot use  or.
 * Assume on this wiki that people know about how Portal 1 is based on Episodic.
 * To find out what games have an entity, check the "what links here" page. The games will be listed, if the list pages are up to date
 * We don't care which game necessarily got the entity first. Info_particle_system was introduced in ep2, but every game before has it too now, so "since episodic/ep2" is invalid.
 * Remember this wiki currently supports 12 games:
 * Half-Life 2 (the three games below should be assumed to be part of "the Half-Life 2 series")
 * Episodic
 * HL2 Deathmatch
 * Portal 1 (first half of Orange Box)
 * CS: Source
 * DOD: Source
 * TF2 (second half of Orange Box)
 * Left 4 Dead
 * Left 4 Dead 2
 * Alien Swarm (not Reactive Drop)
 * Portal 2
 * CS:GO

 * All transclusions of the template add Category:Entities no matter what the parameters are.
 * adds Category:Internal entities.
 * adds Category:Brush entities or Category:Point entities.
 * adds Category:Source partial entities and forbids from adding any categories at all.

 * and add these categories for their different values that are accepted:
