If it's possible to transfer mods from a computer to a 360 (which, I know it is) and someone were to make another online co-op mod (like, or hopefully better than the last), wouldn't that make a type of two player mode accessable on Live?
that seems a bit specific to have been answered officially.... i highly doubt it though.
wait, you can transfer mods from pc to x360?
It's difficult, but not impossible. But to make a long story short, yes; you can transfer mods from a PC to an Xbox, but once they're on your Xbox, they stay there permenantly.
