Half-Life 2, Portal, Left 4 Dead Writer Leaves Valve

Chet Faliszek, writer of Half-Life 2: Episode One and Half-Life 2: Episode Two, among other critically acclaimed Valve games, has left the studio after 12 years.

His departure was confirmed through a statement issued to GamesIndustry.biz, in which he said it was "nothing exciting or drama filled."

"I worked there for 12 years, shipped a bunch of great games and some amazing hardware and wanted to change things up," Faliszek said.

During his time at Valve, Faliszek contributed to the writing of some of the studio's most acclaimed titles. In addition to the Half-Life 2 DLC episodes mentioned above, he also had a hand in the writing of Portal and Portal 2, as well as Left 4 Dead and Left 4 Dead 2.

More recently, however, he has spearheaded developer relations for Vive, the VR headset Valve produced in partnership with HTC.

Faliszek has not provided any details on the next step in his career: "There's no news on what's next," he said in his statement. "I will let you know when that happens."

In February, Erik Wolpaw left Valve. Like Faliszek, Wolpaw's credits include Half-Life 2: Episode One and Episode Two, as well as Portal and the two Left 4 Dead games.

Last year, Marc Laidlaw, primary writer for Half-Life and Half-Life 2, also left the studio. At this point, Faliszek's departure means the main writers on the Half-Life series are no longer at Valve.
