Pause the game as soon as possible (before cutscene)
Select a pair of SC's as they emerge from the MS
Alt-Focus to the [farTop] CryoTray and set the pair
to Salvage an (E)AF
Repeat 3 more times
If you have a spare SC, set it on the [nearTop]
CryoTray (it is the (E)'s first target)
Set the RC to Harvest
Research
Watch the cutscene. Fleet Command lets you know
that one Cryo Tray is "suffering a massive
malfunction." I suggest that this is aka "being under
attack"
Once (E)AF's are 'Secured', go to collect the other
Cryo Trays. (I am told that you can Retire them for
quite a few credits.) You only need to rescue one
but it's easy enough to get all six. The manual p92
assumes you only rescue 5 Cryo Trays. There is no
bonus for extras. One AF is retained in the MS
Build some Support Frigates, Assault Frigates and/or a
Resource Controller so that when you HS out of the
level, you have at least three Frigates beside your MS.
In the next level, a certain number of (E)CSp's are 'made
available' to you, depending on how many CSp's you enter
the level with
