Is there any point in stacking these or just one and done? I just started the campaign and threw on like 3 recruiting offices and it didnt look like it did anything. --- I am a signature virus, please copy me to your own sig to help me spread.
They don't stack. The only benefit to having more than one of a room is that you don't lose the bonus, soldier, etc. when one is destroyed. This could be handy for multiplayer or survival, but it's not really something that comes into play for the campaign in my experience. --- It is the mark of an educated mind to be able to entertain a thought without accepting it - Aristotle
