"As 'Stormers' worldwide continue to collect their FREE Signature Liveries every week, all eyes are turning towards the coast of the setting sun to see what's in store next. We're well aware of what you've all been wishing for – Tracks, Modes, fresh Rides and a few surprises on the side. All wishes, we're very happy to report, that we're about to make come true.
If you're one of the fortunate 40,000 attending E3 at the LA Convention Center on June 2-4, and you're a MotorStorm fan, then you'll be able to count yourself amongst the first in the world to witness our 2 new major downloadable content packs, 'Expansion: SPEED' and 'Expansion: ADRENALINE'. Rammed bumper-to-bumper with new content, you're going to need to set aside some serious time to investigate them both fully."
