Yea I think I've made a mistake with shields, they are meant to be a shield module + an emitter, forcing you to chose between a weapon and shield, but its not clear enough and most games don't do this. Its on my list to review
Is there a way to remove a Module to add another? Also, i like the Idea with the shield emitters in place of a weapon. Now that i understand how it works^^ But yeah without knowing you need an emitter most players will just add the module and wonder why its not working.
