a few other little tips and tricks that help you get your ego up faster do all the side missions. that you can ,
gun lvls peek out at I beleave 20 so just keep reseting the mastery of them and keep your eyes open for beeter virsons.
if you have mods on one gun and find a better version of that gun that does more damage remove all the mods on the first gun and transfur them over to another one. that way you save on scrip.
keep your eyes open for in game events like the dodge chalanager one that's going on. the creaters like to give ups atlof of ingame events and stuff to do so keep your eyes always open for them. thay give out good loot and scrip.
as for utilitys for the game. just from what I have found nad seen on my own. CE dosent do much other then change values. the onlky working utilitys for the game are bay to use ones. that get you busted in a 24 hour period. though iv seen people that don't use tools with weapons so powerfull there droping stuff in 2 -3 shots. o.o it makes me question them because I cant take the time in a major ark fall to check there gear. but still.
on an a side tip to fix one I gave earlier. it seems for a reliabul sroce that you shouldn't open lvl 4 lock boxes till after ego lvl 1000+ because till after then you wont get any with the fire damage or the slag or other damages

well this is all the help full info I have gathered. my only question is are you on PC or on a consul
