Sonic Dash, the endless running game starring none other than the fast-running and fast-rolling Sonic the Hedgehog, has just received its second major update.

Sonic Dash ran into its first major update just over a couple of weeks after its launch in the App Store in early March. That update brought new daily challenges, performance optimizations, and rebalanced obstacles.

As it turns out, Sonic Dash’s second major update also brings rebalanced obstacles. But it also introduces new obstacles that pose different challenges.

Also introduced by the update are new on-track distance markers and new missions. Complete these new missions (all 12 of them) to increase your score multiplier all the way up to x15.

There’s also a new upgradable shield power-up, which, of course, protects Sonic or any other game character you’re playing from harm.

Compatible with iPhone, iPod touch, and iPad running iOS 5.0 or later, the new version of Sonic Dash is available now in the App Store.
