I'm confused about the multiplayer modes in the Half-Life series. Half-Life and Half-Life 2 appear to have launched without online features, but now have paid multiplayer offerings Half-Life Deathmatch: Source and Half-Life 2: Deathmatch on sale, respectively. What confuses me greatly is that Half-Life Deathmatch: Source was released after Half-Life 2: Deathmatch.

Can you elaborate the release history? Did both major releases in the series launch without multiplayer? Are the expansions Opposing Force and Blue Shift (for HL1) and the episodes 1 and 2 (for HL2) exclusively singleplayer content?
