Half-Life 2 Ep 2 demo makes the XBLM colorful

Wowzaz! We've just been blindsided by a new game demo on the XBLM this morning, we didn't even see it coming, but oddly enough we're loving it.

Available for download off the Marketplace to nearly all Xbox Live members around the globe is a brand new, Thanksgiving surprise The Orange Box: Half-Life 2 Episode 2 demo from team Valve. The demo, which we expect to feature only HL2 EP2 fun and not any other Orange Box goods, will take up 732MB of hard drive space and will probably leave you wanting more Orange Box fun ... especially Portal. Speaking of which, we're overjoyed about today's surprise HL2, but where's the Portal demo? We want demand Portal and we want demand cake!
