Groupees is back with another new bundle, this one featuring nothing but original game soundtracks. The Attack of the OSTs!! bundle is available now through August 18th and features an eclectic mix of music and composers new, old, famous and unfamiliar. How eclectic? How about the soundtrack to an existential walking simulator, a handful of mobile games, an old PlayStation PC port of DOOM, and a chunk of Turrican? Take a look at everything up for grabs inside!
