Censor meter. The game is a TV series and the more violent/outrageous things you do the more censored it becomes, increasing the difficulty. enemies wear more armor, the weapons you find get weaker while enemies get laser guns, finally enemies get replaced with deadly robots. The dialog is also affected.
To delay the onset of the censors you need to minimize messy kills and try to keep it clean by targeting certain body parts and using environmental kills like cliffs, but not ones like crushers.
