Treasure is home to a library of some of the most beloved titles in gaming. When Gunstar Heroes was granted a release on the Xbox Live Arcade via the Sega Vintage Collection label, I shrieked in fangirlish glee. While it should have been released on the Sonic Genesis Collection compilation disc, it wasn’t, and I was severely disappointed. What to do save from playing the original or some shoddy applet online? Straight to the Xbox Live Marketplace I went to download this classic ASAP. All I have to say is one word: co-op.
