Op de E3 toonde Ubisoft een indrukwekkende gameplayvideo van Rainbow Six: Siege. Veel fans vroegen zich echter af wat er was gebeurd met Rainbow Six: Patriots, de game waar men hiervoor mee bezig was en die een moeilijk ontwikkelingsproces kende. Op de E3 deed de ontwikkelaar een boekje open over het cancellen van Patriots.

Ubisoft’s technical artist Oliver Couture:  “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].”

Naast de mutliplayer, die in de E3-demo getoond werd, zal Siege ook een singleplayer bevatten. Over de exacte vorm daarvan kon nog niet worden gepraat.
