How to confuse the hell out of potential fans of an upcoming video game: change its name twice during development.
There once was a game called Dirty Bomb, made by the people behind Brink. It later had its name changed to the thoroughly unremarkable Extraction.
It's now had its name changed again. It's not even for a new name. They have just gone back to Dirty Bomb.
While the original excuse given for the first change had to do with trademarks, the devs now say it simply "better reflects its personality".
