I need help, throughout the game I'm getting different weapons, however some have like a purple star or a blue wave type symbol next to them. I understand rare, uncommon, I'm not referring to those colours, but the coloured symbols next to the weapons, what do those mean? Can I get rid of them without worrying that I got rid of something special? Help please! Also, what is the most important stuff to save up for? How do I get legendary marks, any currency info would help, thank you!
