Two new single-player demos have popped on Xbox Live - a second demo for Blacksite and a demo for one of the games included in The Orange Box, Half-Life 2: Episode 2 to be exact.

The BlackSite demo highlights two levels from the game’s single-player campaign, taking gamers through the Rachel, NV town square and courthouse, and placing players in the gunner’s seat during a helicopter escort mission through the desert canyons of Nevada.

And in the HL2:EP2 demo, you’ll get to see how the little train ride that Gordon and Alex started at the end of Episode 1 ends up.
