H&K P90c

The Heckler & Koch P90c was just coming into use at the time of the war. The weapon's bullpup layout, and compact design, make it easy to control. The durable P90c is prized for its reliability, and high firepower in a ruggedly-compact package.

The P90c is a weapon in Fallout 2.

Usage
The P90c is a potent weapon available around mid-game. It has good damage, and costs 1 less AP to fire than all the other burst-type weapons. Because of this, it is essentially the ultimate SMG. Another major advantage of this SMG is that it puts the by then obsolete 10mm ammo, making this weapon fairly cost efficient mid to late game. Although this weapon is still outclassed by the H&K G11E near the end game, P90c is still useful up to that point (even against the super mutants in the Mariposa Military Base).

Characters with certain stats can use the P90c to pop off a devastating 4 bursts per turn. This cannot be done with any other burst weapon. You will need 10 AG, Fast Shot, Bonus Rate of Fire, 2 Action Boys and a P90c in each hand. You can then release a storm of 48 10 mm rounds at up to 4 targets, but you'll need to reload your guns every second turn. Even if you reload both guns, you can still fire 2 bursts and reload that gun on top, giving you another 2 fully loaded SMG's to deal massive damage. If you have the Sniper perk on top of this, you will be a maelstrom of death.

Location
The P90c shows up in random encounters and in shopkeepers' inventories, depending on your level. This is pretty hit-and-miss though.

An easier way to get the P90c can be found in the NCR. Inside the Sheriff's office is a cop named Jack. Talk to him a few times to hear about his ex-wife and how he plans to "show everybody". Rest until morning and head east to the NCR power station. Jack will be inside, threatening to blow himself up. You can then shoot him in the face, or, with high enough Speech, you can talk him down. However, if you want the P90c, Jack must die. Letting him set off the bomb is not enough, you have to kill him yourself.

Shooting him at the power station is 100% legal, and you won't get in trouble with the police. On the other hand, if you take the non-violent path, you can still head down to the jail and assassinate Jack in his cell. This is illegal - the other cops will probably shoot you. You'll have to use Sneak and finish him in one round (i.e. silent death) to avoid stirring up the whole city. This is more of a hassle, but in the end you get more XP, with the same results.

Either way, after Jack's dead, go to the NCR Bazaar and walk into the bar. Talk to Mira the bartender, and tell her you killed Jack. It turns out Mira is the ex-wife. She will give you the P90c as a reward.

An even easier way is to simply obtain it from Vault 15. One of the guards in the third floor basement of the vault carries a P90c with 9mm (it's a bug, as soon as the magazine is depleted it can only accept standard 10mm JHP/AP).
