"Fighting games are very close to my heart, and as someone that's spent much of my life with traditional fighters, All-Stars has been a great opportunity to take a step back and rethink fighting fundamentals from the ground up," writes Killian on the PlayStation blog.
"The entire team was put together from scratch to create this game, and they are loaded with fighting game superstars (including some impressive tournament credentials - I'm not even the first EVO finalist to join the team!) who love great combat just as much as I do.
Describing All-Stars Battle Royale as a "love letter to Sony fans", Killian praised the game's addictiveness.
"Beyond great character designs or all the ingenious little ideas that make combat feel great, the real test of a great game to me is that 'just *one* more game!' feeling.
"If it's 3am and you have to work the next day, but you've still got the urge to play again, you know you're doing something right."
