According to CEO Thomas Hentschel Lund, "It's a challenging game. We really want to keep that. We want to reach that old, hardcore feeling of beating the game. Too many games these days are like rail movies, in my opinion. This is one of those challenging games that you just want to keep trying until you beat it."
"That's part of the fun of playing it. You have to crack the nut of what tactics work," he added, "You have to be a little bit lucky. And you have to executive your plan. But since the AI also knows what you have to do, it's going to try to ruin it for you, and you have to react."
He went on to say that "the core rules are simple, but there are a lot of tactical options."
The simple core rules revolve around the mechanic that each unit has four action points. Points can be spent moving, turning 90 degrees, shooting, and so on; particularly advanced skills may cost two or even more action points. Command Points are special actions that cost no action points.
The game is in complete 3D, along with mini-cutscenes like that found in Firaxis' XCOM: Enemy Unknown. The camera can be zoomed in or out, and can even be zoomed out far enough to render the game in overhead 2D.
Space Hulk is due to be released this Fall 2013 for PC.
