The biggest improvement for this run is that the bombardment is moved closer to where the enemies are, I didn't get as good as a spawning point for the bombardment however.

Moderator notes: User submitted timing as 17.81s. Corrected to 25.533s. Time starts when the scenario dialog disappears, and time ends when every qualifying danger is destroyed or every cryopod is opened, whichever comes later. In this case, the last cryopod was the determining factor.

Moderator edit: Corrected the timing again, this time 15.333s. Opening the first cryopod did indeed open all of them, so the time ended when the last insectoid died.
