The Newcastle studio is aiding the production of "main characters, enemies, RPG pillars, building Manhattan" and its online features. Reflections helped Watch Dogs.
Reflections MD Pauline Jacquey revealed their studio's deep commitment to The Division, which eventually declared itself as coming to PC alongside consoles.
"We've brought a very good design and technological strength to The Division," they told . "Massive's team is bigger, but ours is still significant, and its competency in art, technology and design is really showing."
"There's so much love for this game at Reflections. Our guys are absolutely crazy about it. So for some of them it's a life achievement being able to participate in the development of the game." Reflections has also been involved in Ubisoft's other major projects such as Far Cry 3 and the more recent Watch Dogs.
"We're working on all of the game's systems: main characters, enemies, RPG pillars, building Manhattan, online components, and so on," she continued. "It gives us a very broad and wide input on the game, but it's not as limited as the naval battles on Assassin's Creed III."
Ubisoft now considers it standard procedure to bring on a number of their studios to any given project, particularly the Assassin's Creed franchise which had a globe spanning workforce, with 8 teams alone helping to bring Assassin's Creed IV: Black Flag out for PC and console. Reflections weren't ordered to work with Massive; they wanted to.
The Division releases on PC, Xbox One and PS4 later in 2014.
