Need for Speed World will become completely free.

Starting today EA lifts the level 10 restriction for ALL players of Need For Speed World , which means that now anyone can reach level 50 and gain access to all game modes and locations (current and future) without a Starter Pack
As for those who have already purchased Starter Pack they will receive a small gift from EA in the form of three free rental cars: BMW M3 GTR, Lamborghini Gallardo LP560-4 and Audi R8 4.2 FSI Quattro for 7 days.
