While not exactly a weapon that is used to subdue enemies in Death Stranding, the Sticky Gun is nonetheless an incredibly useful item to have in your arsenal at all times.
This gun essentially fires a wire-shot that allows players to grab, and then pull cargo towards them from a distance. Using this you can literally pull the cargo human enemies are carrying on their backs.
You can even use it on the enemies themselves, and the gun will turn them around, allowing you to then go up to them and knock them out.
To unlock the Sticky Gun, players need to connect the Distribution Center south of Lake Knot City to the Chiral Network.
It’s part of the main story, so you won’t miss it.
