httr4life - sorry, wouldn't let me respond to your comment, so hopefully you get this... you'll find weapon blueprints as early as the boss fight with vor, in "vor's prize." unfortunately i have not been lucky enough to find a braton blueprint, i've only ever been able to buy it from the arsenal. having said that, credits are earned easily through the game. it's platinum you want to save (that's the micro-transaction money). credits you'll have to use to create stuff at the foundry, so it'll be impossible to not spend credits
