David Kirsch

David Kirsch, nicknamed Zoid, is an American video game programmer. His career began when he created Threewave CTF, a highly successful Capture The Flag mod for Quake. He was then hired by id to design this mode for subsequent Quake games. In 2000, Kirsch departed id and was senior engineer of Metroid Prime and Metroid Prime 2: Echoes alongside the late Mark Haigh-Hutchinson at Retro Studios. Today, Kitsch is working for Valve.

Kitsch was working on Retro's Car Combat before it was canceled to free up development for Prime. Kitsch is said to be responsible for the data streaming when traveling from area to area in Prime, and for the Parasite Queen's shield.
