This is my first speedrun. Well, the first official one. I tried my best to make the run as good as possible. CoD4 isn't the best game for speedrunning, but nevertheless I enjoyed running it enormously. This might have something to do with the fact that this was my first real project and thus was something new and exiting. You really need to be an experienced fps player to achieve a good run in this game since most of the time the way to progress fastest in situations is to eliminate all enemies. I used thousands and thousands tries on various situations to get them just right and I'm glad that I pushed myself because I'm finally satisfied with the run.
Some facts: The game has only an autosave option for saving and it's compeletely random at some situations. I edited the videos so that sometimes the segments changes are totally invisible to the human eye. I only ran the missions that are currently up in SDA. Also this run is not done in arcade mode which means no annoying cartoon characters floating around constantly. I also recorded the run in 1280x800 resolution so there's real high quality videos available.

I had a time of 0:53 before I decided to "improve my time". 784 tries and I got it. And for what? A 3 second improvement. Someone slap me.
Total number of segments: 48
