could be more fun for your players than to be in a wilderness
situation and to be confronted by a giant mutant insect? Alien worlds in sci-fi literature are often teeming with interesting life forms. The Wampa ice creature from The Empire Strikes Back is only one example of an animal that presents a major challenge for exploring adventurers.
dangerous is that bug, anyway?
|Offhand, I'd say very dangerous. Run Away!|
animal encounter tables give two numbers expressed in xD for the
animal's fighting ability. The first is hits to unconsciousness, the
second is hits to kill.
Autopistol does 3D-3 (average 8), and is best at Short range or less.
Rifle does 3D (average 10) and is good out to Long range.
Shotgun does 4D (average 14) and is best at Medium range or less.
Laser Rifle does 5D (average 18) and is good at all but Close range.
A character with skill-1 and average DEX will need to throw 7+ to score a hit. That's 58% probability. So we can assume every other shot, more or less, will miss.
