[b]- Night Monsters have a distinctive cry. You'll probably get some warning when one's tracking you.[/b]
[b]- Night Monsters can see in the dark, hear extremely well, track extremely well and move faster than the player.
- Night Monsters are afraid of Z's and will not get within x tiles of them. They won't join regular Z attacks. They avoid cities.
- Night Monsters hate fire and light and will flee from any light sources.
- Night Monsters cannot bash down anything stronger than window. Barricading yourself will protect you.[/b]
- Night Monsters can shred any player within a round or two, no matter what kind of armor you have.
- Night Monsters are not killable. An assault rifle burst will drive one off, but there's no body and you'll never know what it was.
- Night Monsters are not described. Ever. If you examine one, it's just "blurred shapes and dark fangs". Then you die.
THIS.
Parts that are absolutely awesome are highlighted.
I am not too sure about the last three points. Making a creature unkillable is always “tricky”, as it can lead to severe imbalance.
But making them really, really strong should suffice, shouldn’t it?
I like that their strength can be counterbalanced by barricading yourself, that they’re afraid of light (makeshift defence for the early player, just light a nearby fire), and that they won’t join zombie attacks and avoid cities is also nice, as well.
