HtH Evade

HtH Evade is a Fallout 2 and Fallout Tactics perk.

While it states that both item slots must be empty, that is not entirely accurate. It really requires not holding a gun or melee weapon (anything that is visible in the character's hands). This perk will work if wielding unarmed weapons (such as brass knuckles, boxing gloves, power fist), throwables (grenades, rocks), or any non-weapon item.
