R3K

"3-round burst energy rifle. Each burst applies extreme stopping power at precise intervals."

- In-game description.

The R3K is an energy burst-fire assault rifle in Call of Duty: Infinite Warfare. In single-player and multiplayer, it can be transformed form a burst-fire weapon to a fully-automatic weapon, known as the R3KT in multiplayer.

Campaign
When all side missions are completed, the R3K unlocks the Full-Auto upgrade, which initiates a "software hack" that enables the R3K to fire in a full-auto configuration.

Multiplayer
The R3K is available in the assault rifle category from the start, alongside the NV4.

The R3K's EPIC Prototype Weapon variant is the R3KT, which gives the weapon the Break Point gun perk, which allows the weapon to become fully-automatic with reduced recoil.

Zombies
The R3K can be obtained from the Magic Wheel for 950 points in Zombies in Spaceland. Similar to the M1, the R3K has a strong headshot bonus capable of killing a zombie with a single trigger pull. The effect is amplified if the R3K is upgraded, and remains consistent even without the Faraday Slug.

Like most assault rifles, the R3K can benefit from a Stock attachment, allowing more mobility while aiming down sights, especially when training zombies.

When upgraded via the Pack-a-Punch Machine, the R3K becomes the RJ-24, gaining increased damage, a larger magazine, and more reserve ammo.

Trivia

 * The R3KT's name is a play-on on the internet slang word "rekt" meaning 'to be defeated in a humorous and/or humiliating way'.
 * The R3KT variant has the word "PROTOTYPE" imprinted on the left side of the weapon.
