Acid Rain is a mysterious cancelled Playstation 3 / Xbox 360 game that was being developed by Namco Bandai Games USA just for a few months in early 2009, probably by the same team behind their Afro Samurai game. A few concept arts from this obscure project were leaked online some years ago, and while we tried many times to get in contact with people who worked on the game, unfortunately we were not able to get any more details about it.
By looking at these images we can just speculate that the game would have been some kind of action / horror game, and it looks like it could have been an interesting one.
If you know someone who worked at Namco Bandai USA in 2009 and could remember something about Acid Rain, please let us know! In the meantime we’d like to preserve these concept arts in the gallery below.
