Dishonored 2 is a stealth action game that tells you to “play the way you want”. What that really means is that you have a choice in how to get rid of patrolling guards: Either kill them, or knock them out, be lethal, or be non-lethal.
Early in the game I picked up a pistol. Now, late in the game, I’ve still never shot it. Well, except for that one time I shot a wall just for kicks, but my gun has never been used for its intended purpose. It’s never killed people. I also picked up a crossbow early on, and it has been rarely fired. I’ve set insect nests ablaze with incendiary bolts, I’ve broken wood planks with normal bolts, but I’ve only ever shot people with non-lethal bolts. It’s another tool that, for the most part, has not lived up to its intended purpose.
