One minor improvement as well a long-time goal of mine (right on the dot, too)
Defection PA- 2:04
Investigation PA- 2:59.73
Defection... Evil. I speech skipped all of his talking, but had to wait a lengthy amount of time for him to arrive at the terminal. I missed tossing the 2nd ECM mine, and had to waste a few seconds tossing another. Then, I had an odd difficulty of glitching through the wall (don't ask) depriving me of 4 or 5 more seconds.
As for Investigation, it took me around 6 hours to get, with mediocre play the past week. I worked my way down on this level, passing the lasers 7 times total, 3 with bad health and dying at the uplink, and another after the shield tech. The other three I completed first with 3:16 (Very careful... my time with the older strat was 3:18 to give an idea of all the precautions I took), then 3:05, and finally 2:59.73. Ah, and I only got hit once in the drone gun room of death.
Sub-2:50 won't be too difficult for Investigation, but until I try again, breaking 2 minutes on Infiltration PA is my next goal.
