Curt Schilling's struggling video game company, which received a $75 million loan guarantee to move to Rhode Island in 2010, has laid off its entire staff. An email sent by the 38 Studios company to workers says they were notified of the "non-voluntary and non-disciplinary" layoffs on Thursday. 38 Studios moved from Massachusetts after Rhode Island agreed to back the loan. Officials said the deal would bring hundreds of jobs and millions of dollars of tax revenue. "The company is experiencing an economic downturn," the email read. "To avoid further losses ... the company has decided that a companywide layoff is absolutely necessary." The company had 300 employees in Providence. It also has an office in Maryland. It released its much-anticipated first game, "Kingdoms of Amalur: Reckoning," to strong reviews in February.
