Charge rifle

The charge rifle is a spacer-tech weapon that fires 3-round bursts. It has good armor penetration, moderate range, and slightly lower accuracy

Acquisition

Charge rifles can be crafted at a Fabrication bench once the Pulse charged munitions research project has been completed. They require 50 Plasteel, 2 Advanced components, 45,000 ticks (12.5 mins) of work, and a Crafting skill of 7.

Charge rifles can also be found in ancient shrines, or purchased from outlander and orbital combat suppliers, or outlander faction bases. The Rich Explorer starting scenario begins with a single charge rifle.

Human raiders never use charge rifles in RimWorld Core , however if the Royalty DLC is active, they may be obtained from the following Empire pawn kinds:

Raider Kind	Chance	Average Quality	Health
Janissary	?	?	70-230%
Cataphract	?	?	70-230%
Stellic Defender	?	?	100%

Analysis

Charge rifles are endgame tier weapons. In terms of DPS, the charge rifle is only beaten by the chain shotgun and minigun, after considering accuracy. The former has a rather short range, and the latter carries a massive cooldown cycle. The charge rifle has none of their downsides; its moderate range, higher AP, and powerful, three shot burst make it a flexible weapon. A minor downside is that it can't stagger humans.

Charge rifles, as general purpose 3-burst firearms, are very similar to assault rifles. The latter is noticeably cheaper, but also comes with several advantages.

For the same quality, a charge rifle has roughly +20% more pre-accuracy DPS, +50% damage per shot, and twice the armor penetration. At all qualities, charge rifles do more post-accuracy, pre-armor DPS at touch, short, and medium range than an equivalent quality assault rifle and DPS in the long range band is within less than a percent even before accounting for the superior AP. In some specific cases and range bands, this disparity can be even jump an additional quality level. For example, a good charge rifle is superior to an excellent assault rifle at touch and short ranges though remains inferior at medium and long.

However, the charge rifle also has 5 tiles less range, allowing the AR to outrange the majority of enemies and lay fire for longer before melee enemies can close the distance. Therefore, ARs can still be the more appealing choice when a higher enough quality assault rifle is available, or when range is beneficial, such as when kiting.

The main issue with using charge rifles is cost. They require advanced components - which are largely impractical to amass before Advanced Fabrication is available. Raiders outside of the Empire won't ever carry the charge rifle and their appearance in trade inventories is rare, expensive, and limited in quality compared to crafting. For most of the game, you'll have to rely on cheaper weapons. This disparity in cost becomes even more relevant when mass producing weapons in hopes of rolling higher qualities. For example, before AP, a masterwork assault rifle out performs all charge rifles of a lower quality and has superior range, and you can often double the number of assault rifles for the same investment. This makes mass producing high quality, lower tech weapons a viable alternative when resources and crafting expertise are limited.

Stats

Against an unarmored human, a charge rifle can kill with 3 hits to the torso, 2-3 hits to the head, 2 hits to the neck, or 1 hit to the brain; cripple limbs in 2 hits; and cripple or destroy eyes and digits with a single hit. It'll generally take around 5 hits (~9.7 seconds average) to incapacitate that human from pain shock.

Overall, the charge rifle is best paired with a careful shooter up to level 16, and with a trigger-happy shooter beyond that point.

Trivia

According to the lore, charged-shot weapons fire projectiles coated in a matrix of magnetically-contained charged particles. On impact, the energy in the particles is released in a very efficient explosion and greatly increasing the damage done.

In the now-obsolete Quick Primer, charge weapons were also referred to as Tokamak weapons and required high amounts of power to fire. This necessitated powering by hex-cells at small scales (like Charge Rifles), or fusion reactors in the case of large cannons. With the obsolescence of that fiction primer, and the publication of a new primer that omits, but does not contradict, those details, the canonicity of this lore is now unclear.
