I had an idea of adding grapples to fallout dependent on strenght unarmed .Offering situations where the enemy is rendered harmless offering a chance to intimidate or speech checks from the unique dialouge a scenario of this nature would offer wether it's implemented as a perk or learnable out in the wastes.
Thoughts?

If you want them in the next game then this should go http://www.gamesas.com/topic/1370254-fallout-4-speculation-suggestions-and-ideas-thread-62/.

If you want them in this game then this should go http://www.gamesas.com/forum/110-fallout-new-vegas-mods/.

When I first read the OP, http://en.wikipedia.org/wiki/Gr%C4%81pple is the "grapple" that came to mind.

I'm assuming you meant the martial art though.

I thought he meant grappling hook.

Hehe, yeah. Visions of Quake arena.

Isn't this already implemented? Though Terrifying Presence relies on Speech skill and not Strength or Unarmed, it's basically what you've described.

Well the vision I had was akin to say ranger takedown you do a certain input your charcter grabs the enemy (humanoid) and you struggle then speech options arise offering ways o intimdate or other seech options.
