Best Half-Life 2 Discord Servers

Half-Life 2 servers are unusually project-heavy for a game this old. The most active ones are modding communities: Source SDK questions, Hammer mapping help, playtesting builds and release announcements for total conversions. Alongside those sit speedrunning servers trading routes and splits, and general series hangouts that cover the original Half-Life, the Episodes, Portal and Alyx in the same place.

Multiplayer still happens too, with pickup games organized for HL2: Deathmatch and adjacent Source games. If you write it as HL2 or half life 2, you are looking for the same communities.
