Originally named the R-97CN A3, the R-99 SMG was intended for use with the Frontier Colonial Navy, hence the "CN" classification. The Colonial Navy would often conduct Orbital Boarding Parties on hostile ships in high orbit or entering the atmosphere, so they needed a weapon platform that was compact and had the ability to spit lead downrange in low gravity or in extremely confined areas such as cockpits or ship corridors. In Apex Legends the R-99's rate of fire is second to none as it dumps a full mag into try-hards in a matter of seconds.
