Escape Plan Underground DLC is now available to buy from the PlayStation Store priced £1.59, developer Fun Bits Interactive has announced.
Underground joins Lil and Laarg as they ride an elevator into the depths of Bakuki's Underground. The new area is filled with a convoluted network of trains, trolleys and minions.
The DLC also features Furry and Tourists costumes, plus new challenges and trophies.
Underground will return to its regular price of £3.99 as of August 15.
Game update 1.03 is also ready to download, offering new Buzz and Flower Power Summer Pack costumes, and the addition of squeeze control to the circle button.
