On November 4, 2015 it was announced that fellow Fullscreen subsidiary ScrewAttack would become a division of Rooster Teeth and Let's Play. Its website was updated to be consistent with Rooster Teeth's branding, along with all its previously existing users becoming Rooster Teeth users and its forums being absorbed into Rooster Teeth's forums.

The website is primarily known for the web series Death Battle, in which they pit pop culture icons against each other in a fight to the death and determine who would win. Other content includes an animated fight show without research called DBX, a podcast called Death Battle Cast, an informative show called Desk of Death Battle, and Top 10 lists.
