Here's another brilliant cinematic sequence from the guys at Valve. It was about a year ago that I posted some other Team Fortress 2 Character Trailers, and I'm glad to see they're still making them! Great writing, design and animation, and a healthy dose of sex and violence.
And in case you missed this one (like I did) here's Meet the Sniper. Enjoy!
UPDATE: You can see all the character movies in high quality here.
