This week we're joined by Mark Estdale, founder of leading voice production firm OMUK. Drawing on his experience directing actors for games ranging from best-selling PlayStation blockbuster Horizon: Zero dawn to Telltale's Game of Thrones series and indie hit hue, he discusses the elements that add up to a great performance in video games.

We discuss a brief history of voice acting in games, the reasons why A-list screen actors aren't necessarily best suited to the medium, and the importance of giving performers as much context as possible when they record.

There is also advice for studios looking to add voice acting on a low budget - even phone recordings can be of use - and how aspiring actors might get started in the field.

As always, you can find more news, analysis and insight into the world behind video games at www.gamesindustry.biz.
