To respect the state of mind of the Predator in his hunting he must use hunter weapons and not war weapons.

I think a harpoon will be interesting to hunt. The prew who is hit by this harpoon will be bring and if the Predator can hurt the prew in the safe place. But the prew can struggle and try to escape or attack (with QTE for example ).

Another Predator accessory that may be interesting : A energetic shield. In Predator 2 movie we can see a scene in the subway where the Predator didnt have damage by Jerry’s gun. So may be the Predator can use his energy to create in a few time a concentrate of energy to protect him against the fireteam of commando.
