yes there are things that spawn from tiberian, i think in firestorm there are missions where there are weird monsters that are really strong and they spawn from tiberian and theres this one monster you prolly seen more often is like this little gooey thing its like green and the green stuff you ore is tiberian and if infantry go in it they get hurt and can die and spawn stuff i think and if you need help just go look at gamefaqs.com they have lots of strategy guides
