Bungie touted Destiny as a revolutionary video game to a tiring degree, but it turns out they may have been right. Arguably the best-controlled first-person shooter out now, Destiny was looked at by Bethesda during their development of Fallout 4 and took cues on how guns should fire and reload.

In a new story by Game Informer, “The Making of Fallout 4,” director Todd Howard admitted that Destiny was a perfect template because it shares some crucial technical similarities to Fallout 4. Specifically, how Destiny presents action at 30fps, the exact framerate that Fallout 4 will run. Bethesda also hired former Bungie developer Josh Hamrick to concentrate “intently on tuning firearms.”

“The main difference in the way we develop … is that we will develop with as many knobs as possible,” Howard said. “We’re always thinking of scale. We’re not a team that is just going to make eight guns and spend forever on one gun. We knew we were going to have thousands, so we needed to develop a gun system that had all of the dials.” This isn’t surprising given that Destiny players go through hundreds of different guns throughout their careers, all of which play wildly differently from the other.

Back in June, Howard said Fallout 4 will possess vastly-improved shooting over its predecessors while still retaining the Fallout flavor. The VATS system, a series signature that allows players to target areas of their enemies while action slows down like a Zack Snyder movie, will be back in Fallout 4.

“We started out with Fallout 4 knowing that, look, we can’t apologize for being a role-playing game,” Howard said in an interview with GameSpot.”We have to build a first-person shooter, and it needs to be a really, really good one.”

Fallout 4 will be released on November 10 on the Xbox One, PlayStation 4, and PC.
