Quite a while ago, in February 2014, we learned that Sony Santa Monica canceled a PS4 game, causing a sizable round of layoffs at the studio, and creating one of PlayStation's best guarded mysteries.

Today, industry insider Shinobi602, who is well known for having solid sources within several studios, provided some more details about it on NeoGAF, including the code name "Darkside."

"Darkside was definitely an interesting concept. RPG mechanics, customization, vehicles, post apocalyptic open world...things just didn't come together, milestone reviews failed. Trying to get that action-melee combat working with guns wasn't easy."

"Also had a somewhat similar UI/HUD to Dead Space."

Shinobi also mentioned that the project wasn't up to par.

Unfortunately, it's unlikely that we'll ever get to see anything of the game with our own eyes. As usual, considering that the information doesn't come from an official source (even if Shinobi basically never disappointed with his information), take this all with a grain of salt, but it's certainly interesting.
