Recent 2.0 update brought many new features to Sonic Runners, including the new timed game mode, a new interface, and the infamous walls of spikes ( now gone, thanks to the many complaints). But some of them are buried inside it’s innings.
Thanks to some datamining sessions, DaGuAr from Spanish site Sonic Paradise found some interesting secrets hidden inside the update. He found the already intuited Christmas costumes for Sonic, Tails and Knuckles, probably from a incoming Christmas event. Along with it, Mephiles from the infamous Sonic 2006 is also present.
