Dart Feld render.
Playstation All-Stars Battle Royale is a Super Smash Brothers-like crossover video game released for the Playstation 3 and Playstation Vita by SuperBot Entertainment in November of 2012. SuperBot and Sony broke away from eachother, and DLC duties were given to Sony Santa Monica Studios, the makers of God of War.
The Missing DLC
DART FELD
In 2013, they announced all DLC for the game would be cancelled. The fans of PSASBR found concept art from a developer of the game that showed that Dart Feld, a very requested character from the video game "Legend of Dragoon" would be a playable character in the game as DLC.
ABE
Journey/Gravity Rush stage.
Someone also confirmed that Abe from Oddworld: Abe's Oddysee was supposed to be part of the DLC too. This eventually caused the #ReleaseDart Campaign. This campaign did not work.
STAGES
There was also talk of a stage that would crossover the video games Journey and Gravity Rush, but little is known about them and they did not come into existence either.
