I've recorded the gameplay. As you can see,the level has changed. The images in gallery will be changed soon. So for now, the first level is completed.
First noticeable thing is that removed box from the middle. It was really ugly. Fun fact, box cointained crowbar and headcrab. Also, I changed lights and room in first Combine fight section. There is now gate,and the computer doesnt seel anymore.
I also added some fixes after publishing video. The APC car isn't sunken anymore, and bin has changed its place.
