How is having the briefcase any easier than just starting out with a guard disguise and conspicuously having a sniper rifle stuck to your back?
We’ve had the briefcase in every Hitman game, and it’s worked fine. They were doing to include it in H6, but were apparently constrained by technical issues. They even teased us with a Hitman Briefcase PS4! We’ll get it sooner or later, and then we’ll have the CHOICE of using it.
By any objective standard, more options means more diverse playthroughs, and that’s always what makes Hitman appealing.
