Rage HD is an on-rails shooter set in a post-apocalyptic world, which should already be enough to intrigue the shooters-starved iCrowd. Gritty shooters aren't exactly thriving on the iOS platforms after all, are they? Well, no, sadly not, though this one is a really good one. What's more, with Rage being created by FPS legends/tech-gurus id, you should expect some truly impressive graphics; probably the best you've ever seen on your iPhone to be a frank. Oh, and, as the ever vigilant Savygamer noticed, Rage HD has now gone free to grab. Better hurry and grab your postapocalytpic copy now methinks.
