Hello. I've not long jumped on to Evolve and so far I'm enjoying it. There's not a lot to it granted but enjoyable all the same. Anyway, I have been going through character progression but I've noticed something that I can't find an explanation for and wonder if you can shed some light. After doing a certain amount of damage with my lightning gun it gained a star, now though I can't seem to progress it to the second or third star no matter how much damage I seem to do now. Am I being thick? Is the second and third star not damage related? Ive tried to find anything in the options but can't see anything other than a global tooltip. I'd like to level my stuff :( please help
