Because one leak before the official announcement wasn’t good enough, the PlayStation All-Stars Battle Royale official website leaked new fightesr Sackboy (from LittleBigPlanet) and Raiden (from Metal Gear Rising: Revengeance) yet again, this time with artwork to share.
(Ratchet, also leaked, is there, too.)
Additionally, if you zoom in on the artwork featured in the Raiden shot:
You see Jin Kazama and Kazuya Mishima from Tekken, and Ryu Hayabusa from Ninja Gaiden:
Ratchet (from Ratchet & Clank), who was previously leaked, is also there too.
The leaked content has since been removed.
Thanks, NeoGAF.
