Which Half-Life writer is credited as one of Dota 2's writers?

Which Half-Life writer is credited as one of Dota 2's writers? Marc Laidlaw is the answer.

Laidlaw was a Valve writer best known for his major role in the Half-Life series, including Half-Life, Half-Life 2, and its episodic sequels. Dota 2's credits also identify him as a writer, reflecting Valve's use of internal writers to develop hero dialogue, lore, and the game's broader fantasy setting.

A common mix-up is Erik Wolpaw, another prominent Valve writer associated with Half-Life and Portal. Chet Faliszek also worked as a Valve writer, while Jay Pinkerton joined Valve later and is associated with other projects. Laidlaw left Valve in 2016, but his Dota 2 credit remains part of the game's development history.

Dota 2 launched in 2013 as Valve's standalone successor to the Warcraft III mod Defense of the Ancients. Its writing helped preserve the original game's characters while giving them a distinct setting separate from Warcraft.
