Frima Studio will release its upcoming 2D "couch co-op" adventure platformer, Chariot, for PlayStation 4 this fall, executive producer Martin Brouard announced via the PlayStation Blog.

In Chariot, players guide a chariot through underground levels. The game uses physics-based mechanics, meaning players must push, pull, ride and reel their chariot along. The game is "designed for multiplayer shenanigans," Brouard said, but still includes single-player options.

"Chariot is the story of a princess whose task is to lay her father's remains in his final resting place," Brouard said. "With the help of her fiancé, she has to take this heavy chariot holding the king's remains through underground mazes in order to reach a sepulcher fit for His Majesty.

"However, the king's ghost, bound to the chariot, has quite a temper and insists that he be buried with vast amounts of riches. Exploring and collecting loot in the caves therefore becomes an essential part of the game."

According to the executive producer, the idea for Chariot came from creative lead Philippe Dion. An early prototype of the game won the team over.

"Even though it was entirely done with stick figures, we knew we were on to something when we watched people playing together, arguing and teasing each other, and really having a great time goofing around," Brouard said.

More details about the game are expected as it nears its launch — a date that "isn't set in stone," he added.
