Halfquake Sunrise Testing and Accidents
Whenever I was stuck, I liked opening a small map and just throwing things together to test out ideas or to see what I can come up with. The accidents were also made separately (in the video you can see one that wasn't used) and then copied to the actual maps.
The video has no sound because it wasn't recorded. I suggest you hum a tune yourself while watching, or tap to an imaginary beat with your foot. Here, I'll give you a tempo: 1, 2, 3, 4 - *nods at you*
