Essentially I get to level 19 and to the final missions after fending off the invasion. At this point I don't have a high enough level to fabricate anything else am unable to really make any progress because I constantly am defeated by the big queen each time I try.
I know this seems like a really dumb question, but how the hell do you attack? It says to LMB but that doesn't do anything? Is there something I'm missing? (Extremely new to the game btw
