Competitive online games are a rapidly growing industry, driven by the explosive popularity of eSports. Titles like League of Legends, Dota 2, Call of Duty and Overwatch dominate the professional gaming scene, and studios across the globe are implementing competitive modes in their games. Robot Entertainment, the studio behind the tower defense series Orcs Must Die, is no different. "I can't tell you everything, obviously, but we're always working on some maybe head-to-head competitive style gameplay with this," Orcs Must Die Unchained designer Jerome Jones says. "We have to figure out the right way to do it. For Robot, the "right way" means keeping the series' lighthearted tone alive while adding eSports elements to the core game. "One of the things that's important to me is to maintain our humor and our feel," Jones says. Back when Orcs Must Die came out, we sort of created the genre, a third-person tower defense game. So now we want to stay special, if you will."

With the next series of Game of Thrones set to hit our screens this month anxious fans may be wondering which one of their favourite characters is next on the hit list. The first five of the series have not been an easy watch, with the writers killing off key characters just when their luck starts to change and as audiences warmed to them.
