I've been casually speed running System Shock 2 often since 2006, so it's about time I actually publish a run. It's been almost 6 years since the previous run was published, yet I was only able to make an improvement of 0:03:12 due to how solid the previous run is, both in route and execution. A lot of people have had a chance to see that run already, so in these comments I'll mostly focus on what I did differently. Those interested in more detailed commentary can check out the audio commentary for the run.

At the beginning of the run, I strafe run up the fallen debris, rather than getting the wrench and knocking it down. This saves a few seconds.

Pretty early in the run, in hydro, I pick up a SwiftBoost implant which I use to replace the useless (in a speed run) BrawnBoost implant. The extra point of Agility doesn't help a lot, but it saves a little time overall.

Later on in the run, in Operations, I get Psychogenic Agility. It saves time by not only making me run faster, but by allowing me to jump straight from the rocket to the ladder in the Rickenbacker, without having to use the teleport trick.

When confronting Korenchkin, I save some time by teleporting out of the area as soon as I destroy his phantom, which allows me to get past his psychic barrier to the Rickenbacker without having to take the time to destroy his brain. I would say this saves around 30 seconds, and is probably the single biggest improvement over the previous run.

There isn't much else to mention. The audio commentary I've recorded goes into greater detail about the run, including tricks that were in the previous run. Not recommended for those who aren't as autistic about this game as I am (extremely).
