What determines how much resources you would yield from a raid?
You may only take 50% of targets total resource value provided you have enough cargo capacity.
Large amounts of BS most of the time don’t require and Large Cargo.(Battleships tend to have a nice storage capacity) If u dont have a lot of BS(Battle Ships) spy on planet add up total resources and divide by 2 and send in enough Large Cargo to take that amount of Resources.
you scan someone and he has
200.000 metal, 150.000 Crystal and 100.000 Deuterium.
He has total resource value of 450.000 / 2 = 225.000 = 9 x Large cargo depending on how many other ships are going.
You will get half of each te resource as well if u have enough ships so in this case you would gain 100.000 metal 75.000 crystal and 50.000 Deuterium. You wont gain equal amounts if player does not have equal amounts.
I hope this clears everything up :)
Voidhawk’s Note: You can also use SpeedSim to determine how many Large Cargo (or Small Cargo) ships you need to send.
