Publisher Square Enix has released the debut trailer for Life is Strange Episode 4 ahead of its release date on July 28.

Entitled 'Dark Room', Episode 4 follows Max as she pursues her investigation surrounding the disappearance of fellow student Rachel Amber. This fourth and penultimate chapter will ship on PlayStation 4, Xbox One, PC, PlayStation 3, and Xbox 360.

A promotional blurb from Square Enix reads: "As the End of the World party approaches, Max must use her powers to put all the pieces of the puzzle in place."

Meanwhile, Square Enix has also revealed that Life is Strange has surpassed one million sales since the release of its debut episode in January. "This is a huge achievement for the small team working on the game," the publisher said.

Developed at Paris studio Dontnod, Life is Strange has been widely praised by critics for attention to detail in depicting student life, along with how a time-reversal mechanic is threaded into its gameplay.

GameSpot's Life is Strange Episode One Review described it as "an involving slice of life that works because its situations eloquently capture a peculiar early-college state of mind." Reviews for Episode 2 and Episode 3 were similarly positive.
