Grand Theft Auto V has become one of the best-selling game of this generation, with Take-Two shipping a massive 80 million units since it launched on Xbox One, PC and PlayStation 4. The company also introduced GTA Online and it has become one of the publisher's biggest revenue streams since it launched the feature.
However, a stuntman by the name of Tim Neff updated his iStunt resume recently, and one of the projects listed that he was allegedly working on was Grand Theft Auto VI (6). The sixth installment of the series has been rumored for a while now, and this could be the first of many leaks to come if it exists. Stunt actors are used in game development for motion capture, especially in high-risk scenarios where the main actors might not be capable of achieving the results required by the specific scene - much like in movies and TV shows.
Take-Two however, hasn't confirmed the existence of the title yet, instead focusing on the upcoming Red Dead Redemption 2. The publisher recently delayed the launch of Red Dead Redemption 2 from this year to 2018, noting that it wanted to 'give the game time' to develop and be the best that it can be, and the success of the GTA franchise is clearly giving the publisher some breathing room. In 2015, Rockstar hinted that it already had ideas for the next installment, although it did not know what the game would be yet.
Although you should always take these rumors with a truck load of salt, it will be interesting what Rockstar and Take Two come up with in the next installment if it exists. In the mean time, you can check out the GTA V on your favorite console or PC.
Update: Tim Neff updated his profile. It was changed to Grand Theft Auto 5 instead.
