The games' Facebook page currently has around 41,957 'Likes', but it'll need to hit 100,000 before anyone can get their hands on the goods for zilch.
It'll only take two seconds (providing you already have a Facebook account) to head over there and click the 'Like' button, so what's stopping you?
In case you don't know, RAGE is an on-rails shooter that sees you skirmishing with hordes of mutants in a post-apocalyptic TV show.
You have three weapons at your disposal - pistol, shotgun, machine gun - a melee attack for when things get up close and personal, and the ability to dodge incoming attacks.
As you battle through each arena, you can grab bags of cash and ammo supplies, work your way up several leaderboards, and unlock Game Center achievements.
Both versions of RAGE received updates just yesterday, giving them better compatibility with iOS 4, HDMI TV output, and a new control scheme.
If you don't want to wait for the inevitable sale (are you mad?), you can grab RAGE on iPhone for 69p / 99c / €0.79 and RAGE HD on iPad for £1.49 / $1.99 / €1.59.
