Sega is planning to reward Sonic fans for their platform loyalty when it launches Sonic 4: Episode II on Android.
You see, if you already own Sonic 4: Episode I on Android, and are planning to pick up the next episode on the same device, you'll be able to unlock a special bonus story free of charge.
The extra content - entitled Episode Metal - puts you in the chrome shoes of Sonic's shiny nemesis, Metal Sonic, and aims to fill in the missing story between Sonic CD and Sonic 4: Episode II.
According to the chaps at Sega, you'll have to put Metal Sonic back together as you zoom across four reimagined acts from the first episode.
While we can't be too specific at present, we can reveal that both Sonic 4: Episode II and Episode Metal will be sprinting onto Android in June.
