Achievement Hunter

2008–10: Inception and growth

In 2008, Geoff Ramsey's interest in gaming achievements resulted in the realization that no community-based website related to achievements existed. As a result, Ramsey approached Burnie Burns, then CEO of Rooster Teeth, about creating a website based on achievements; Burns agreed, and Ramsey created Achievement Hunter, which shares a similar design to the main Rooster Teeth website. Ramsey later elaborated, saying he had grown tired of making Red vs. Blue and enjoyed working on this new, creative outlet in his spare time. Alongside employee Jack Pattillo, Ramsey regularly released achievement guides and Easter egg videos, often receiving assistance from select volunteers from the Rooster Teeth community. David Dreger also assisted in the founding of the site.

2011–12: Employment growth

In 2011, Achievement Hunter hired Ryan Haywood as an editor and manager; Haywood later began being featured in videos as a host in March 2012, becoming one of the main crew members. Four new shows were introduced to Achievement Hunter in 2011. One of them, Rage Quit, led to the official hiring of Michael Jones as a full-time staff member in August 2011.

In December 2011, Achievement Hunter also began creating Let's Play videos. The success of the videos resulted in a weekly sub-series in 2012, in which the main hosts play Minecraft. Weekly Let's Play videos focusing on Grand Theft Auto games are also released.

Achievement Hunter hired Gavin Free in 2012, after he had assisted with the company for many years. In March 2012, Achievement Hunter debuted Game Night, in which Ramsey and Caleb Denecour play games with community members; the series switched to a live stream format in 2014. Community member Ray Narvaez, Jr. was hired in April 2012, having worked as a contract host for multiple years. Later, in September 2012, contract editor Franco Scarcello created Five Facts, which was generally hosted by Pattillo and Ramsey and focused on little-known facts about various video games; it was not renewed for a sixth season in May 2016.

2013–present: Popularization

In early 2013, Achievement Hunter introduced a competition series titled VS, in which the employees challenge each other to compete in games. In April 2013, Achievement Hunter launched their own channel on YouTube, which hosts a variety of their videos. Later in 2013, the company retired Achievement HORSE, replacing it with Achievement HUNT, in which a variety of employees challenge each other until the word "HUNT" has been spelled.

In October 2013, Pattillo hosted a 24-hour live stream benefiting Extra Life, a charity benefiting hospitalized children. With appearances from other Achievement Hunter members and various Rooster Teeth employees, the live stream managed to raise $340,000. This charity live stream has become an annual event, with 2014's Extra Life live stream raising over $442,000 for Children's Miracle Network. At RTX in July 2014, community members Matt Bragg and Jeremy Dooley were hired as editors and secondary hosts at Achievement Hunter.

In early 2015, Achievement Hunter hosted the first Let's Play Live at the Moody Theater in Austin, Texas. In April 2015, Narvaez departed from the company as a full-time employee to focus on Twitch livestreaming, although he continues to voice his character for the company's X-Ray and Vav animated series. In mid-2015, Achievement Hunter launched a new YouTube channel, named after themselves, thereon they upload series of videos that were previously uploaded to the Rooster Teeth channel. Additionally, they moved out of Rooster Teeth's Stage 5, Austin Studios office into their own office nearby.

Dooley was promoted to a main host in October 2015, during an episode of Let's Play Minecraft. A weekly podcast titled Off Topic was announced in early October by Michael Jones. Four test episodes aired live and were only available to "Sponsors" on their website. The first official episode aired to the public after the initial tests. Jones serves as the main host of the show and makes the most frequent appearances alongside other Achievement Hunter employees and special guests.

From 2015, Achievement Hunter would feature celebrities as guest collaborators in some of their Let's Play videos such as Rahul Kohli, Dan Campbell from The Wonder Years, Laura Bailey, Travis Willingham, Dante Basco and pop punk band Neck Deep.

Let's Play Live!

Let's Play Live! is an on-stage event produced by Rooster Teeth in which the Achievement Hunter members play video games and perform comedy sketches in front of a live audience. Their first event was held on February 20, 2015, at the Moody Theater in Austin, Texas. On September 14, a documentary was released about the event for sponsors on their website.

In 2016, three more Let's Play Live! shows were held, with the first at the Dolby Theatre in Hollywood, California on June 17, the second at the Chicago Theatre in Chicago, Illinois on August 19, and the third at the Hammerstein Ballroom in New York City, New York on October 8. These events also feature appearances by other members of the Let's Play family; Funhaus, ScrewAttack, Kinda Funny, Cow Chop and The Creatures.
