Pulse rifle (Fallout 2)

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

Background
An electrical pulse weapon was developed by the Yuma Flats Energy Consortium.

Gameplay
The most expensive weapon in the game at 17,500 caps, the YK42B pulse rifle has the highest damage per shot of any rifle. Combined with its Weapon Penetrate perk, this makes it the most armor-piercing energy weapon in Fallout 2, dealing heavy damage against even the most high-tech protective gear.

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.

Despite its strengths, the YK42B is hardly an all-around weapon suitable for any and every tactical situation. Its range of 30 hexes is shorter than those of the other high-end rifles, 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, the YK42B does little non-critical damage against floaters, which are a fairly common enemy in the former American Southwest and highly resistant to electricity. 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.
