youre pretty much screwed
VPn's wont allow that much traffic over them.
They are too slow for gaming
I have an idea though
A friend of mine was in a similar situation, so what he did was to contact the tech support people for the game to ask their advice.
they told him how to configure the game so that it connected over a different set of ports using different protocols
HOWEVER, I suspect that what your college has done is to limit the upload speeds
and when gaming, they are just as important, if not more so, than the download speeds
