The slimes that slither out of the eggs in Duke Nukem 3D do not play nice with the other enemies. Despite there often being guards around egg clusters, if the eggs hatches and you leave the area and let them have some time with each other, only the slimes will remain after a short time. This behavior is one tactic to ensure enemies do no return in the highest difficulty setting of the game. However, it appears that not every enemy is susceptible to spontaneous liquidation. Octabrains seems to avoid this grizzly fate but who else?
