EA has released debut trailer for Sims 3: Ambitions, the second expansion pack. The trailer provides a brief glimpse at the careers your Sims can pursue.

Detective, firefighter, and scientist are just some of the roles available in Ambitions. You directly control your Sims while they're at work and determine how their careers proceed. The skills they pick up will allow them to earn "Simoleons" (see what they did there?).

Ambitions is targeted for a June release for the PC and Mac. A version for mobile phones should arrive later in 2010.
