The YK42B is an electrical pulse weapon that was developed by the Yuma Flats Energy Consortium. It is considered a far superior weapon to the YK32 Pulse Pistol, having a greater charge capacity and range.

The YK42B pulse rifle is an energy weapon in Fallout 2.


虽然和脉衝手雷有着相似的名称,但YK42B脉衝步枪严格地说起来并不是一种电磁脉衝武器,而是一种使用电脉衝杀伤破坏电子器材及有生目标的装备。 YK-42B是废土上最为昂贵的武器之一(17,500 caps),它的单发伤害超过了二十三世纪能在北加利福尼亚找到的任何一种步枪,而它对电子原件有着额外破坏力的属性也使得它在对付动力盔甲这样的装备是非常地有效。

The YK42B pulse rifle does a whopping 66 hit points of average damage against unarmored foes. Against medium-heavy and maximally heavy personnel armor, it averages 33.24 and 22.54 HP per shot, respectively. This weapon's critical damage is almost unparalleled, with critical hits to the eyes capable of surpassing 300 HP and averaging well over 150 HP against most enemies.

For a character with an average Critical Chance (5%), eye shots from this weapon do more average damage against the heaviest armor types than what point-blank bursts from most machineguns do, at the same action point cost.

不过,它的威力只能在较近的距离上(30 hexes)发挥,而且对于不熟练的使用者来说它的瞄准方式十分地不友好, preventing the player from immediately targeting the farthest enemies in some encounters that occur on desert plains. Secondly, unlike the other high-end rifles, the YK42B lacks both the Weapon Long Range and Weapon Accurate perks, thereby requiring an extremely high skill for accurate aimed shots to be possible at its maximum range.

Thirdly, as an electrical pulse weapon, 在对付浮游特这种表皮绝缘而且极厚的怪胎的时候,它的杀伤效果也相对有限。Armor-piercing critical hits circumvent this problem though.

On the other hand, the YK42B pulse rifle (together with the alien blaster) is the most effective single-shot weapon against Frank Horrigan, whose only weakness is his low resistance to electrical damage.



  • Scoring a killing blow on an enemy with either a critical hit, Bloody Mess trait or simply a powerful enough attack will reduce them into a pile of ash. Thus, any items they were carrying get scattered on the ground nearby and have to be picked up one by one. This can be avoided by turning the violence level down in game settings.
  • The YK42B, unlike the YK32 pulse pistol, doesn't fire a visible purple projectile.
