I'm here to save everyone some time and annoyance:
Space Port Catastrophe is an okay map, a bit on the more boring side but not bad. It's included as a Bonus Mission in Reactive Drop, making this campaign pack pretty pointless considering how bad the second map is.

Train Station Investigation on the other hand is infuriatingly bad in terms of design. Two objective critical hack stations are poorly placed, one is facing away from the default camera angle making it easy to miss if you don't know what you're looking for, the second is at the top of the only ladder that can be climbed and required to break (wooden) crates blocking your path to the next objective. If you're playing the map for the first time, you'll find that one at the entrance of the map, rotate your map CCW once to see better.
Instant death traps are ignored by bots, meaning they'll kill themselves on them during the final section of the map preventing Single Player from getting a no death runs most of the time.
