Rapper Machine Gun Kelly has launched his own video game.

The rising star, real name Richard Baker, released a prototype of the project, Nun Puncher, on his official website this week (begs03Dec12). The game encourages users to knock out knife-toting women wearing habits.

Fans can consume energy drinks to boost their performances and those with high scores can sign up to win merchandise and other prizes.

Urging followers to check out his latest online venture, the 22-year-old Lace Up hitmaker tweets, "How many nuns you punched?"

Baker isn't the only music artist to release his own video game in recent weeks - dance music superstar Skrillex recently launched Skrillex Quest, which requires players to fight off a technology glitch in order to save a character named Princess Keys.
