Parodic 8-bit open world game Retro City Rampage has been updated with mod support and enhanced graphics. Not massively enhanced, mind. You're not going to load up the game to be dazzled by a city rendered in full 3D. But you are going to see twice as many on-screen colours, and "realtime soft shadows", which is more than the NES could handle.
VBlank's Retro City Rampage has been a long time coming, but a release date has finally been unearthed. The 8-bit crimefest will be on like Donkey Kong on October 9th, which the eagle-eyed among you will realise is... today. $14.99 - or about £9 - will get you the game on GOG or Steam, although if you buy it direct from the developers you'll get a DRM-free copy plus either of the above.
