The creator of PlayerUnknown's Battlegrounds (PUBG), Brendan Greene, has apologised after a controversial female character model with 'camel toe' made its way to the game's test server on PC.

PUBG Corporation, the recently renamed team behind the hit online shooter, came under fire for the apparent sexualisation of female characters in the game, with many fans taking to social media to voice their dissatisfaction.

If you don't know what a camel toe is, we'll let Urban Dictionary explain.

On Twitter, PUBG creator Brendan Greene said: "After looking into this, it appears it came as part of the character model we received from an outsourcer when we first started the project.

"The file itself has not been changed in two years. It will be updated shortly with changes! Sorry for any offense caused."

The offending crotch renderings will soon be removed from the test server, and will not make it into the full, wider game.

The news comes as PUBG makes its debut on consoles as an Xbox One exclusive available through Microsoft's preview program for early access titles that release in an unfinished, ever-changing state.

That was the case with the initial PC release back in March. The game has proven a global phenomenon since, selling more than 20 million copies worldwide. On 20 December version 1.0 will be released, ending the game's time in early access.

In PlayerUnknown's Battlegrounds, 100 players are airdropped onto a large island map where they compete solo or in squads to gather equipment and fight to be the last competitor or competitors standing in an ever-shrinking area of play.

The game started life as a version of Arma 2 mod DayZ.
