Rage was released over a year ago, but recent evidence suggests it'll be getting new downloadable content that may feature a new job class called "Scorchers".
This evidence comes from ten new Trophies added to the PlayStation 3 version of the shooter, with five Trophies revolving around said "Scorchers". One Trophy is unlocked for finishing the single player campaign on "Ultra Nightmare difficulty" as well.
Earlier this year, PEGI listed "Rage: The Scorchers" for PC, Xbox 360 and PlayStation 3. It'll be interesting to see if this ties in with the developer John Carmack promised as well.
