I used to play a game back in the late 80s, early 90s perhaps. It featured mutated beasts. Every player had to choose a creature to play. The creatures all had a special ability and room on their sheet to add upgrades. These upgrades were weapons if I'm not mistaken. I think there were maximum 6 or 7 creatures to choose from.
Possibly the name of the game was something with "mutants" or "nuclear" in the title.
I remeber playing it alot but I actually don't even remember if it was good or not. Regardless, I've been trying to find it here but up till now, unsuccessful.
I'm confident you guys will be able to help me on this one
