Yea they really are fun to use too. Can't wait to learn new unarmed moves. Btw I'm level 3 playing hard - hardcoe mode.
Heh, at 75 skill you get "Cross". Unarmed becomes godlike then. Higher damage move (I believe) that knocks enemies backs and often drops their weapon to the ground.
First place you'll normally see the Spiked Knuckles is in Primm. The Casino (Vikki & Vance) has a room with several safes, it's there with several other objects in one of the opened safes.
I saw the Vermint Night Scope or whatever it's called in Chet's store in Goodsprings. But that was with my unarmed char - he was only selling one weapon mod (as opposed to 3) for my guns one.
Another really good early weapon is found in Primm. In the Bison Steve hotel, there's a "Hard" safe with a revolver named Lucky. With decent guns, it does something like 40 damage per shot at 120 DPS. After I got it, it took me like 8 hours to replace it with something better, didn't even bother with the Cowboy repeater - same ammo but pales in comparison (damage-wise).
