Here’s a quick announcement: I just open sourced NuclearWinter, the set of XNA libraries I’ve been working on and off for the past year or so (both on my own time and at Creative Patterns).
NuclearWinter contains a wide range of useful stuff for making 2D games for Xbox 360 / PC / Windows Phone 7. The main feature is the ability to turn SVG files into level or UI sheet files!
Right now the libraries lack documentation & samples but I hope to provide some soon. In the meantime, feel free to dig into it, use it, and contribute back if you’d like to!
Thanks to the guys at Creative Patterns for allowing this to happen!
