Thief 4 producer details how DualShock 4 will be used on PS4, how AI component and stealth are intertwined

Thief 4 producer producer Stephane Roy has discusses the game’s AI component with the PS Blog, stating that thanks to PS4 architecture, the team could push the immersion further than with PS3.

Elsewhere in the interview he discusses the DualShock 4 features in the game, such as how the light bar and touch pad will be used.

“For the DualShock 4, we use the light bar to reflect the light gem in the in-game UI, which indicates if Garrett is in the shadows or not,” said Roy. “It creates a nice feeling when you play in the dark to see it illuminate or darken as you move through the environment. Additionally, the touch pad allows for better menu navigation and makes for a more intuitive way to perform various actions, like navigating the map or selecting weapons.

“What impressed us were not only the new features of the DualShock 4, but how the existing ones have been improved. The best example of that is the motion control, which is way more precise than before. You can use it to adjust your aiming with the bow and the level of accuracy we get with it is really impressive.

“The last thing is the Share button. We think it’s a great addition, especially for a game like Thief. We give a lot of freedom to the player, and we work really hard to create a systemic AI that will let the player find creative ways to play. Sharing those moments will showcase how they solved various situations — and we’re pretty sure that players will find ways that impress even us.”

Rpy also touches upon the stealth mechanic, and how it pertains to the AI.

“When people think about the stealth in Thief, the first thing that comes to mind is the light and shadow,” he said. “It is the core of our stealth, but it’s not only about that. We have a complex perception model that creates realistic situations. Being in the shadow reduces the visibility of the player, but the position of the player, their movement, and the distance all change how the AI perceives Garrett.

“We also model the sensors of the AI as realistically as possible. We distinguish between central vision and peripheral vision. This also is put forward by the way we use head tracking to make the AI look more believable when they react to something and look at the player.

“And there is also the sound that will attract and alert AI. Players can control the sound they emit by controlling their movement speed, but it’s also influenced by the surface they walk on.
Together, these elements create a realistic AI, but also an AI that’s fun to play with, that the player will be able to distract, evade, and try to outsmart.”

Thief arrives on PC, PS3, PlayStation 4, Xbox 360 and Xbox One in February 2014.

    I suppose trying to sell it as a next gen game is their last recourse now since selling it as a Thief game has failed. What bothers me is that if they realiseed they were diverging so far from Thief to create a Dishonored clone, they could have just not called it Thief.

    When I think of Thief, I don’t think of Dishonored’s setting, nor do I think of a very one-dimensional Robin Hood character who doesn’t look the least bit aged or rough-from-life. I could even have settled for a new character if they hadn’t called him Garrett, honestly. Yet they took this boring, flat character and slapped the name of a better one on him.

    They’d honestly have done better with a names that had nothing to do with Thief or Garrett, because then it could have been judged on its own merits. By taking upon the Thief moniker, they’re taking upon one of the most interesting settings gaming has to offer, and assuredly one of the most interesting characters. So it just feels like an insult.

    So I guess all they can do is this, now. Trying to sell it as a next gen game that PS4 owners will want. Hell, maybe if young PS4 owners don’t have any connection with Thief or Garrett, and perhaps if they don’t understand the rich character and setting history that’s been stolen away from them, they won’t care. So that’s all they can do now.

    Or, hey, they could have not called it Thief. There’s that. And if they desperately needed to call it Thief, they could have at least tried to be honest to the lineage.

    It just bugs me because Thief is one of my all time favourites. You’d probably guessed. Even Deadly Shadows was a damned faithful Thief game, because for all of its flaws, at least they got Garrett and the setting right. Which are the two most important things for me.

    I just hope this isn’t a reboot and this is the setting and Garrett we have, now. Because if it is, it’s time for a spiritual successor. And I recommend Frictional Games for that role, as I genuinely believe they have what it takes. I keep thinking of their game engine and writing skills, and I can’t think of anyone else who could pull it off better.

    @#1 All I read was ‘Wah wah wah it’s not the same game I played all those years ago with the same dated mechanics that feel like clunky rubbish now, wah wah wah.’

    The game looks and sounds like it could be intense and fun, and even though I loved the original games, you know back in the day, I’m looking forward to a fresh look at it. I don’t care if it feels like a Dishono[u]red clone because like people arguing that the Tomb Raider reboot was an Uncharted clone the argument stinks.

    Stop living in the past and look to the bright shiny future ahead of us!

    @2: People could look ahead if the game was an actual improvement that offered new features, with an interesting multi dimensional character, set in an interesting diverse world. If the gameplay truly improved or even blazed new trails then it could be called a bright future. Instead what they did was take a watered down crappy game that morons like yourself will snatch up and slapped a classic franchises name on it.

    Before you say I’m living in the past and disregard what I said with such a childish response like you did #1 let me tell you that I’ve never played the original Thief games. My only experience with the franchise was Deadly Shadows and I thought it was alright at best. I’m also okay with Reboots if done properly. The old was good, but I welcome the new. Sadly what we are being given as new is not something to look forward to.

    @2: You did good, son.

    @6: “Instead what they did was take a watered down crappy game that morons like yourself will snatch up and slapped a classic franchises name on it.”

    Ah, so you’ve already played it then? What do you mean “No”? But … there has to be a reason why you’d say all those things, otherwise that would mean that you’re full of it.
