Since

Usually it's not simple to quickly and compactly define which games a feature is available in without listing everything, therefore this wiki is using few keywords like in, since, before, all to simplify this and sometimes it may not be entirely accurate. In case of using also in or only in it's straightforward what's meant when it comes to particular games but not so much when it comes to engine branches.

Tip:If unsure what games an entity is available in check dump_entity_sizes page which lists all for each game. (entity being listed doesn't guarantee it's fully supported for the given game)

Meaning of since when used with games

• (in all games since ) - means available in Half-Life 2 and all Source Valve games released afterwards
• Template:L4d - means available in Template:L4d and all Source Valve games released afterwards (see Source games in the release order ↓)
