StarCraft II's new community web site has continues to add content in preparation for Tuesday's launch Blizzard's sci-fi RTS sequel. The site has now added two new videos which we have reproduced here. The one you see above this post gives the basics of the game's single player campaign without going into too much story detail. The other video goes over how the game uses the new Battle.net system for various features. You can check out that video after the jump.

The site has also posted a detailed game guide going over the basics of the game, the multiplayer units, the various worlds and races, StarCraft II's cast of characters and more.
