Metal Gear Solid 5 isn't exactly short of options for approaching its open-ended stealth scenarios. But encouraging players to use every tool at their disposal can be difficult once they've found a loadout that they like.

But this solution didn't go far enough, at least according to MGS 5 modder mohtalgear. And to celebrate the sequel's tenth anniversary, they decided to do something about it, resulting in the Definitive Subsistence Update.
