Mini-crossbow

The Mini-crossbow was specifically developed for espionage work and accepts a range of dart types (normal, tranquiliser or flare) that can be changed depending upon the mission requirements.

The crossbow is one of the weapons Paul offers to you at the start of the game. If you don't pick it up there, a NSF troop outside the Statue of Liberty has it. Otherwise it can be found throughout the game on enemies, in crates and lockers, or simply lying on the ground.

Tactics
The crossbow is extremely useful in pacifist runs. It's the only ranged weapon that can knock out enemies, so you'll be relying on it a lot. Try and put a scope on it ASAP, since you'll need all the range you can get. Accuracy mods will also help, even if you do upgrade your Pistol skills. Range mods will help get over it's low accuracy range, so use them on the Crossbow as soon as you get them. Clip mods do not work with it, so get used to having to reload after four rounds.

In non-pacifist runs, some players may find the crossbow almost useless since its darts do little damage and tranquilizer darts take a while to kick in (although flare darts are fun to use, but rare). Other players, however, may find it useful since it only takes up one inventory slot and can be used to knock out almost any enemy if the player is patient enough and has enough darts. Some players may find the crossbow useful early in the game, when long range shots are difficult and single-round kills even more so. In these situations, shooting a guard with a tranquilizer dart and retreating to safety for a few seconds may help the player to avoid a costly firefight.
