The iPhone version of Sonic The Hedgehog 4 is soon to include Game Center functionality.
The iTunes description for the platform legend’s newest instalment now states that an update – to be submitted to Apple on October 15th - will give Sonic 4 compatibility with Apple’s online gaming community.
Quite what kind of functionality it'll get isn't clear, but we reckon it’s more likely to be leaderboards and achievements than a full-blown multiplayer.
Sonic The Hedgehog 4 came out on iPhone this week to generally positive reviews. You can buy it now for £5.99 / $9.99.
