La première vidéo mise en scène de Rainbow Six: Siege nous avait laissé de marbre, mais les parties filmées durant l'E3 en situation réelle sont déjà bien plus intéressantes. On y voit un jeu multi jouable en 5v5 et se déroulant en deux phases :  
 
Durant la préparation, les terroristes se barricadent tandis que les flics envoient un drone pour les espionner et repérer l'otage. Ensuite démarre la seconde phase où les forces spéciales approchent de la maison, y pénètrent et se fraient un chemin jusqu'à leur objectif.
 
J'ai beau chercher un jeu comparable, il n'y en a pas vraiment. C'est plus rapide et orienté action que SWAT 4, c'est moins nerveux et moins compétitif que Counter-Strike, on détruit tout comme dans Bad Company 2 et à côté de ça c'est bourré de gimmicks et de gadgets à la Ubisoft. Entendez par là un HUD et un gameplay pas du tout crédible qui vous rappellent à chaque instant que vous êtes dans un jeu vidéo.  
 

 
    “To be completely transparent, I worked on Patriots – on Rainbow Six for three-and-a-half years – and Patriots was old-gen. Xbox 360 and PS3. Next-gen consoles were just around the corner, and we were like, ‘OK, we want to also have a next-gen experience. What can we do for that?’ We were trying stuff out with destruction technology, and we realized destruction really changes the game. We tried to see how it could fit with old-gen, but it just didn’t work out. So for us it was just a better solution to clean the slate, reset, and make what’s best for the players.”
 
    “We’ve been working hard for the past year-and-a-half [on Siege].”
 

 
    “We know that single-player is also an important part of the Rainbow Six experience. We understand that while this year we showed multiplayer – because we want to have fun playing against each other internally, it’s a good test to know if a game is fun – but we are 100 percent aware that single-player is a big part. We’re currently working on that too.”
 
    “The scope of the single-player is not completely clear yet, so I cannot really elaborate on it. All I know is that the message we have on the production floor is like, ‘All the comments online, people are always talking about single-player. So we’re gonna have something for them.’ But I can’t say if it will be more cinematic [like Patriots was] yet.”
