Brooker wrote for "PC Zone" magazine in the mid and late 1990s. Aside from games reviews, his output included the comic strip "Cybertwats" and a column titled "Sick Notes", where Brooker would insult anyone who wrote in to the magazine – and offered a £50 prize to the best letter. One of Brooker's one-shot cartoons caused the magazine to be pulled from the shelves of many British newsagents. The cartoon was titled "Helmut Werstler's Cruelty Zoo" and professed to be an advert for a theme park created by a Teutonic psychologist for children to take out their violent impulses on animals rather than humans. It was accompanied by photoshopped pictures of children smashing the skulls of monkeys with hammers, jumping on a badger with a pitchfork, and chainsawing an orang-utan, among other things. The original joke was supposed to be at the expense of the "Tomb Raider" games, known at the time for the number of animals killed, but the original title, "Lara Croft's Cruelty Zoo", was changed for legal reasons. In October 2008, Brooker and several other ex-writers were invited back to review a game for the 200th issue. Brooker reviewed "Euro Truck Simulator".
