The OVERKILL Software website informs us the Spring Break event is underway in PAYDAY 2, the heist sequel (thanks rist3903). This will involve daily events over the next week, and here's word on the first day:

HEISTERS! As the first reward on the Spring Break tour, we’ve taken two old heists and have had our level designers update them. We’ve taken day 1 of the Rats job and made it into a stand alone heist where you can cook for however long you want. We’ve also taken the Train heist and made it into a stand alone heist, changing up the gameplay in order to improve the experience. This means more choices for you and a better experience for everyone – and of course, two more achievements for all you achievement hunters out there.
