Counter-Strike is updated for the modern era today on PSN. It's joined by Retro/Grade, NISA's Legasista, Way of the Samurai 4, whose trailer you absolutely must see, and a few somewhat less drastic remakes and updates than Counter-Strike: GO!
Said refreshes include Metal Gear Solid 2 and 3, separated out from the HD Collection and released digitally, Jojo's Bizarre Adventure HD, and Gungrave: Overdose, which isn't actually updated at all – it's a PS2 Classic. The ability to download it and play it on PS3 is new.
