Five months after the release of Starcraft 2, Blizzard has finally released a demo of Starcraft 2.

The demo can be downloaded from Battle.net and includes the first three single-player campaign missions and the skirmish mode. Although in the full game, the skirmish mode requires a Battle.net account to play, in the demo that is not the case. The Starcraft 2 demo is 1.56 GB and can be downloaded right now over at Battle.net.
