Overwatch is Blizzard's first foray into the console shooter market, so the studio enlisted the help of a veteran shooter maker.
Call of Duty: Black Ops 3 devs helped Blizzard have good aim assist in Overwatch
Being the studio's first console shooter, the Diablo and World of Warcraft studio wanted to make sure Overwatch played well on a controller.
"We actually worked with some of the Treyarch guys to make sure our aim assist [on controllers] felt really good, they were really helpful," assistant game director Aaron Keller told GamesRadar.
"The funny thing is, we collaborate with a lot of different Activision studios," he added. "We collaborate with the Destiny team, when they were building Destiny they wanted to talk to some of the people at World of Warcraft to see how they made some of their content.
"And we've gone to Treyarch a number of times and talked to them, whether it's about some of their guts of the engine features, or whether it's about tuning changes. And they've come out and looked at some of our stuff, too."
We've recently played the console version of Overwatch and found it pretty solid.
Overwatch is out May 24.
