SG3N-A03 is a credit bought shield generator which gives 5,000 shield strength, and absorbs 60% of the damage inflicted. This shield is an alternative until one has enough uridium to purchase an elite shield generator.
This shield generator is one step up from SG3N-A02, and is the best credit bought shield. It provides greater shield strength, but lesser absorption, than the SG3N-B01 and SG3N-B02 which cost Uridium.
The SG3N-A03 can be bought in the Shop for 128,000 credits.
