With the PlayStation Store reactivated and back online after falling victim to a series of well-coordinated cyber assaults, Sony finally introduced its Welcome Back program on Friday to placate the thousands of angry clients.

The PSN outage began last month when tech giant Sony's PSN was attacked leaving as many as 100 million user's account and billing information compromised. The hacking of the PSN network cost Sony over $172 million, close to the amount that the company had to cough up after the Japan earthquake and tsunami damage in March.

Still struggling to win back public trust, the company has announced that they have restored the PlayStation Network and Qriocity services.

The Welcome Back program will allow all PSN members who had signed up before the outage (April 20, 2011) to select two games for the PS3 system and two games for the PSP system. In addition, users will also have access to the premium subscription service, PlayStation Plus, which includes games, huge discounts, exciting exclusives and added features like online storage and automatic downloads, for a total of 30 days at no charge, requiring no long term commitment.

PSN users will also get 100 virtual items in PlayStation Home while the current Music Unlimited Premium subscription members will receive an additional 30 days of premium subscription plus days lost due to the outage.
