Character mistake: When the Level 3 Sentry gun is revealed on the right of the screen and fires a rocket barrage to the left, you hear it explode as the Engi looks over. You then hear Scout scream "My arm!" really loud. Then an disembodied arm falls in front of Engi with a plop. However, this arm is from the character model of Sniper, not Scout. Including his glove and his watch. (00:00:45)
Audio problem: As the camera pulls back from the truck, a Pyro is running up at the Engi from the left side. When the Level 1 Sentry turns and kills him, the Pyro makes the Sniper's death cry. (00:01:10)
Continuity mistake: Towards the beginning of the video and just a little bit later, you see bullets hit the truck behind the Engineer and leave clear, large bullet holes. These holes are very visible and stay in the same spot. But as the camera is pulling back and you see these large holes still there, you can see sparks jump off the truck a couple more times in two more spots near the Engineer's head. However these shots leave no holes while the older holes remain visible. (00:01:10)
