When Call of Duty: Warzone came out, everyone expected a refined game with smooth control and gameplay, not a PUBG 2.0 with full of bugs, making the game really annoying to play. This is definitely not what many players were expecting. If the developers cannot fix these problems soon, they will lose lots of players.
Vehicles can kill a player behind walls
Recently, a player posted on the Call of Duty: Warzone subreddit about a bug that caused a truck to kill him behind a wall. Vehicles are a great tool in Call of Duty: Warzone for players to move their squad quickly and safely on the map. But vehicles also have a secondary use to kill other players by crashing into them. However, they weren't supposed to kill players behind a wall.
Many players also complained about the unusually high HP of vehicles in Call of Duty: Warzone, making vehicles in Call of Duty: Warzone indestructible moving fortresses.
Winning a game from Gulag
In Call of Duty: Warzone, players have a second chance to win the game after they have been killed by other players in a prison called Gulag. If you can win a 1vs1 match vs another player here you will be free and sent back to the battlefield.
However, this player didn't have any opponent at all when he was sent to Gulag. As a result, he stayed there safe and sound until the end of the game.
Meanwhile, the circle kept getting smaller and smaller until there is no safe space left. The actual winners died because of the poisonous eventually and his team won the game from the prison.
