I did not know where to put this topic for a global vision. So I put it here.
Always have Dutty ready for projects
When you buy a white duty box in StarBase (750 fleet credit), it is by default bounded to the character.
In order to un-bound, proceed as follows :
1) Buy several boxes of dutty in the starbase (max : 50 per slot).
2) Split them (with the Ctrl key, regardless of the number), note that the newly created pack is no longer linked to character.
2) Merge bound pack into un-bound pack.
Now, you have a dutty's pack you can put in the bank.
For the sake of fairness, the rule is that whoever uses these boxes to complete projects buys new boxes with fleet credits earned.
Earn fleet marks
The best way to earn fleet marks quickly is to organize private "No-win-scenario" and leave at the beginning of wave 10. (No cooldown so immediately repeatable, 300 fleet marks *5 in less than 10-15 minutes).
Getting to wave 10 is quite easy as long as all players use the right vessels and follow the right builds and tactic.
Beat wave 10 is quite harder, but not impossible (500 fleet marks *5 and a very prestigious accolade).

Tactic
The biggest DPS place himself to face North waves (Stay at 2-3 km from cargo)
The second DPS place himself to face East waves (Stay at 2-3 km from cargo)
The western and southern waves are less difficult, place 2 people to face them (Stay at 2-3 km from cargo).
So there must be a player at 4 cardinal points around the cargo (2-3 km).
It is REALLY important that each player stay focus on their direction and don't move!!! (because of bio-neurals at higher waves).
Last player used to always switch and provides support for the most challenging waves.
Here is a video to illustrate the tactic.
