Suicide Squad: Kill the Justice League is a follow-up to the Batman: Arkham series from developer Rocksteady Studios, but it doesn't take much more than a glance at the game to realize that it's a substantially different experience overall. Although it's no surprise that playing as a squad of villains will yield a unique bent compared to a stint as the hero, the change in approach goes significantly beyond this basic shift. That being said, there's still a lot of common ground between Suicide Squad: KTJL and Batman: Arkham for those who enjoyed the past Rocksteady titles.
