A: Sorry for the lack of clarity! You are not missing any cards from the deck. Those are symbols which appear on Goals to make it easier to designate a class of cards. You’ll see a little more info about them at the top of the second page of the instructions.
Though they are not marked with a specific symbol, any card with “Human” or “Humans” in the title… has humans. That would be almost all of the Creepers (except for The Army and Germs) and one Keeper (Humans In Black). We felt that putting a “human” symbol on every single human card would be a bit redundant, since they all literally say they are humans. We did much the same thing in Zombie Fluxx, using a sort of skull symbol to designate “any Zombie” when we needed to indicate that for Goals, but we didn’t put that symbol on every Zombie Creeper in the deck. These things take up space!
The same for the Female symbol on Goals. I suppose we could have specifically labeled those Humans which should officially be considered “female” but we didn’t want to get into any complicated gender stuff here. It’s just a game. Any human which appears to you to be female would count as “a female of the species”. If you have players who want to get nitpicky about how some of the images are drawn, go through the deck with them and make official rulings on each card and add the symbol yourself. Hopefully people won’t get too bent out of shape about this.
Likewise, you may find mention of hats on one of the Goals. We didn’t make a special symbol for “having a hat” either. If the human looks like they are wearing a hat, they are, and we made sure the Beauty Queen clarified her headgear, as she was the only one we felt was a bit ambiguous.
Hope that clears things up! If you do want to check the card list on line, just in case you are actually missing anything, it’s here:
