For those of us who didn't quite make it to BlizzCon, here's a very big treat courtesy of Gametrailers - the complete Story Mode video walkthrough of StarCraft II. Trust us when we say this - this is a must-watch, more so if you've been itching to know more about the game besides the tons of info we've already reported on.

In this mammoth four-parter of the Story Mode walkthrough, we get a sneak peek at how Jim Raynor's aged. While he somewhat follows the tradition of badasses becoming even more badass with age he's definitely in his own league, having broken away from former alliances to fight on his own. We also get a look at how the briefing screen looks like - no more talking portraits and heads, they're actually there in the scene with Raynor.

Best part of the walkthrough? Right at the tail end of Part 3 - where the guy conducting the demo uses a cheat code to unleash two high-end Terran units, the Battlecruiser and a giant beast of a mech to finish the mission he's just taken.

StarCraft II is definitely looking better and better. Enjoy the videos!
