Excellent!
Xtremedevil, just because you don't understand something is no reason to rate a movie of quality like this down. It is based around the game Half-Life 2. The thing he's riding on is a Strider, sort of like a spider-legged tank, from the game. I also assume the chickens are a reference to the ones back in Counter-Strike 1.5. They were removed from Counter-Strike: Source to my knowledge, so Breen rescuing a chicken has a bit more meaning than you might think. Then again, I might be reading too much into it :P
I particularly liked how you brought the animations from what looked like in-game rips directly into the movie. That and the entire animation was very smooth and detailed. The sound was brilliant, very high quality, and it definitely had its funny touches to bring a smile :P I'd say this definitely deserves a 5. It was a great effort on your part, and definitely worth everyone's time to watch!
((Rated Violence 0 because there wasn't any, and Interactivity 5 because there is a working menu. Neither of these factor into the Overall score.))
