Despite the inherent goodness of their previous games, Q-Games' upcoming PixelJunk 1-4 was never going to sell with a name that sounded like a Mario Stage. So it's been changed to something more marketable.
And that name is PixelJunk Shooter. The title was settled upon after users were allowed to nominate their own ideas for a name, and since the game involved shooting, Shooter was the winner (Actually, PixelJunk Elements was the winner, but it didn't work out, so Q-Games binned it).
Mike's had a go on the game already, and liked what he saw, so until the game's release during the Summer you can read up on his impressions here.
