This run is very flawed, but it uses the mute-trick which makes it much faster. There are no strategical upgrades compared to my last WR. The only special thing here is mission 7. The cutscene at the beginning is so short, that it glitches the camera to be unmovable. I fix this by reloading the game file, but it looses a lot of time. If anyone figures out a way to unlock the camera or to play the mission with a locked camera, they are likely beating my time.
