Hey, so I have had some time to figure out how it can be done.
Did a full legit solo run on my marauder of colicoid wargames. Turret phase was (yes) a mild challange.
The only real problems arose at the first puzzle, everything else was cake after that. (Though I assume without leap second puzzle would also pose a challange, might try working it out on a non-leap toon as well.)
Here is an SS with me behind the door that blocks the path to the console clearing he puzzle:
Kudos to the one who can guess how I got through! (there was no cheesing at all by going outside of the fp and around the puzzle, like when a juggie soloed it while back).
