A classic Titanfall gun is also one of the best to use in Apex Legends, the battle royale set within the same universe.
The R-99 is a beast. It has an incredibly high fire rate, the fastest in the game. So if you hit your shots up close, you can one-clip a fully shielded enemy. With level three attachments, it becomes even more lethal.
The downside to the R-99 is its range and recoil. As a submachine gun, it will falter in long-range encounters when compared to assault rifles like the R-301 or even light machine guns like the Spitfire. The R-99 is meant for CQC battles.
Here's the R-99's weapon statistics in Apex Legends.
