Vikkstar – which has more than seven million subscribers on YouTube – said the game was “the worst state ever”.
Warzone was released last March and has been played by over 50 million people worldwide.
The publisher, Activision, previously stated that it has a zero tolerance for cinemas.
The UK-based Wikstar – whose real name is Vikram Singh Byrne – explained why he was going to a video on YouTube.
“The game is in the worst case ever, with Activation not really finding out how many hackers are in the game,” he said.
“It needs to be fixed otherwise it will actually be the death of the game.”
The video also shows the gameplay, where while playing the game, Wickstar claimed to live up their antics on Facebook.
“What an absolute joke,” he said.
“We just happened to catch these people, but often you don’t even know what people are doing that we’ve just seen.”
He said hackers could be encountered in almost every lobby of the game.
It comes a week after another popular Call of Duty dreamer, NickMercs, announced that he would no longer compete in tournaments in sports.
In a stream on Twitch, he said: “All kinds of hacks … there’s no pride in [playing the tournament].
“Where is the honor? Where is the honor system?”
Last April, Activision published a message on its blog, stating: “There is zero-tolerance for theaters in the warzone.”
“We take all forms of cheating very seriously, maintaining a level and fair playground for all is our top priorities,” he said.
“This is an area we are heavily working on, but it is not always something we discuss publicly.”
The blog said that the company has issued more than 70,000 permanent restrictions on accounts since the game’s release.”We believe that there is no single solution to deal with theaters, it is a constant enforcement every day, 24/7. Be assured, we are committed to ensuring a fun and fair experience for all.”
The BBC has contacted Activision to respond to the latest complaints.
An example of how players can cheat is by using a so-called “ambot”. This allows precise shooting of competitors without having to manually aim.
Another popular hoax is a “wall hack”, which allows the user to see the location of other players in the game, and attack them through opaque objects such as walls.
Other hacks let users hide and conquer by default, or heal themselves infinitely.
“Typically, writing these pieces of software is difficult, but easy to install,” said Sam Connolly, an expert in computing at the University of Central Lancashire.
“Cheats are often downloaded by hackers and installed with relative ease on their own computers.
“Call of Duty has always had a history of hackers … unfortunately this is an issue that is not unique to one type of game, but seems to be very widespread in first-person shooters.”
Players have called for Activision to implement anti-cheat technologies to address the issue.
Other games, including Fortnite and Fall Guys, have developed software to deal with attempts to unfairly win their own Battle Royal-player-standing titles.
“One issue with this type of anti-cheat software program is that real players will be mistakenly banned in a big way, and the embedding process is generally quite dangerous,” said Ampere Analysis senior analyst Lewis Schotherhouse.
“There have been suggestions of hacking during the official Warzone tournament, which is extremely damaging to the competitive integrity of the Call of Duty brand.”
Activision recently announced plans to bring Warzone into its professional e-sports Call of Duty league.
“Without addressing the cheating problem, its success and reputation as an e-sport will undoubtedly suffer,” Ms. Shorehouse said.
